This is the Vocab24 daily quiz of 28 August 2026, the same 26 questions the app served that day, on the day's vocabulary and editorial. One mark for a right answer, minus 0.25 for a wrong one; the explanation opens as soon as you tap.
Out of the given alternatives select the alternative which best expresses the meaning of given word.
SUPERINTEND
Explanation: Superintend means to supervise, oversee or remain in charge of an activity or organization. Oversee therefore expresses the meaning most precisely. Centralize concerns concentrating control, internalize means bringing something within an organization and interpret and pool convey entirely different ideas.
Out of the given alternatives select the alternative which best expresses the meaning of given word.
INSECTIVOROUS
Explanation: Insectivorous describes an organism that feeds on insects and entomophagous carries the same meaning. The remaining alternatives refer to feeding primarily on plants, grains, fruits or plant matter and therefore express contrasting rather than synonymous ideas.
Out of the given alternatives select the alternative which best expresses the meaning of given word.
BIOFUEL
Explanation: Biofuel is fuel produced from biological materials such as plants or organic waste. Biomass fuel is therefore the appropriate synonym. Petroleum, natural gas and coal are fossil-based energy sources and are specifically opposed to biofuel in the given vocabulary set.
Out of the given alternatives select the alternative which best expresses the meaning of given word.
CONICAL
Explanation: Conical means having the shape of a cone. Tapering most closely reflects this shape because a cone gradually narrows toward a point. Cylindrical, spherical, cubical and flat describe geometrical forms that are specifically contrasted with a conical form.
Out of the given alternatives select the word opposite in meaning to the given word.
INSECTIVOROUS
Explanation: Insectivorous means feeding on insects whereas herbivorous refers to feeding on plants and is therefore an appropriate opposite. Entomophagous, insect-feeding and insect-eating reinforce the original meaning while insectivore is a closely related noun.
Out of the given alternatives select the word opposite in meaning to the given word.
SOCIALISM
Explanation: In the vocabulary set, socialism is associated with collective or state control of major resources and industries. Capitalism is listed as its opposite. Collectivism, public ownership, common ownership and social ownership are all conceptually aligned with socialism rather than opposed to it.
Out of the given alternatives select the word opposite in meaning to the given word.
CROWDSOURCE
Explanation: To crowdsource is to obtain ideas, information, services or funds from a large group of people. Centralize expresses the opposite tendency because it concentrates activity or control rather than distributing participation among a large group. The other alternatives are associated with the collaborative sense of crowdsourcing.
Out of the given alternatives select the word opposite in meaning to the given word.
BOUTIQUE
Explanation: A boutique is a small fashionable shop specializing in distinctive products. A department store represents the contrasting idea of a much larger retail establishment with numerous categories of goods. Shop, store, outlet and emporium are instead listed as related synonymous expressions.
Out of given alternatives, choose the word which can be substituted for the given words/ sentence.
A microscopic organism, particularly one such as a bacterium, virus or fungus.
Explanation: Microbe is the precise one-word substitution because it refers to a microscopic organism, especially a bacterium, virus or fungus. Biofuel is a biological energy source, ammunition refers to materials fired from weapons and boutique denotes a small fashionable shop.
Out of given alternatives, choose the word which can be substituted for the given words/ sentence.
A political and economic system in which major resources and industries are owned or controlled collectively or by the state.
Explanation: Socialism exactly corresponds to the stated definition because it emphasizes collective or state control of major resources and industries. Crowdsource is a verb concerning public participation, boutique is a type of shop and biofuel is an energy source derived from biological material.
Out of given alternatives, choose the word which can be substituted for the given words/ sentence.
Fuel produced from plants, organic waste or other biological materials.
Explanation: Biofuel is fuel produced from biological materials such as plants or organic waste. A microbe is a microscopic organism, ammunition consists of materials fired from weapons and socialism refers to a political and economic system rather than a source of energy.
Out of given alternatives, choose the word which can be substituted for the given words/ sentence.
A small fashionable shop dealing in specialized or distinctive products.
Explanation: Boutique is the correct substitution because it refers specifically to a small fashionable shop selling specialized or distinctive products. The remaining options denote a microscopic organism, weapon supplies and biologically derived fuel respectively and therefore cannot substitute the definition.
A statement with one blank is given below. Choose the set of words from the given options which can be used to fill the given blank.
Despite possessing the intercepted transmission, the intelligence unit could not ______ the message until it identified the underlying coding pattern.
Explanation: Decode means to convert a coded message into understandable language or discover its meaning and therefore fits the context precisely. Encrypt would perform the opposite process. Superintend means supervise, crowdsource involves obtaining assistance from a large group and centralize concerns concentrating control.
A statement with one blank is given below. Choose the set of words from the given options which can be used to fill the given blank.
Instead of depending entirely on fossil fuels, the project proposed converting agricultural and organic waste into ______.
Explanation: Biofuel is the appropriate choice because it is fuel derived from biological materials such as plants or organic waste. The reference to replacing fossil fuels reinforces this contrast. Ammunition, socialism, microbe and boutique belong to entirely different semantic categories and cannot logically complete the statement.
A statement with one blank is given below. Choose the set of words from the given options which can be used to fill the given blank.
Rather than allow a small internal committee to generate every proposal, the organization decided to ______ innovative suggestions from a much larger online community.
Explanation: Crowdsource is appropriate because the organization is obtaining ideas from a large group, particularly through an online platform. Internalize would suggest keeping the process within the organization and therefore conflicts with the context. Decode, superintend and encrypt refer to entirely different activities.
Out of given alternatives select the option which best expresses the meaning of given idiom/ phrase.
Insect-feeding
Explanation: Insect-feeding expresses the idea of consuming insects and is therefore equivalent in sense to insectivorous. The other choices describe frugivorous, granivorous or herbivorous feeding patterns and represent contrasting dietary habits.
Out of given alternatives select the option which best expresses the meaning of given idiom/ phrase.
Public ownership in the context of an economic system most nearly refers to:
Explanation: Public ownership is associated with socialism, under which major resources and industries are owned or controlled collectively or by the state. Privatization and unrestricted individual control are closer to the opposing concepts listed with capitalism and individualism rather than to public ownership.
Out of given alternatives select the option which best expresses the meaning of given idiom/ phrase.
Biological fuel most nearly means:
Explanation: Biological fuel is given as a synonymous expression for biofuel and refers to fuel produced from biological material such as plants or organic waste. Petroleum, coal and natural gas are fossil energy sources and therefore represent the contrasting category.
Which of phrases given below each sentence should replace the phrase printed in bold type to make the grammatically correct? If the sentence is correct as it is, mark 'd' as the answer.
The engineer was appointed to superintended the construction of the new research facility.
Explanation: After the infinitive marker to, the base form of the verb is required; therefore to superintend the construction is grammatically correct. Superintended is a past form, while superintending cannot normally follow the infinitive marker in this construction. Superintendence is a noun and cannot function as the required verb.
Which of phrases given below each sentence should replace the phrase printed in bold type to make the grammatically correct? If the sentence is correct as it is, mark 'd' as the answer.
Some microbes are useful to producing medicines and fermented foods under controlled conditions.
Explanation: The construction useful in producing is grammatically appropriate and expresses the function performed by microbes. For produce incorrectly uses the base verb after a preposition and to produced combines an infinitive marker with a past form. The original construction to producing is also ungrammatical in this context.
Which of phrases given below each sentence should replace the phrase printed in bold type to make the grammatically correct? If the sentence is correct as it is, mark 'd' as the answer.
The company decided to crowdsource ideas for its new advertising campaign.
Explanation: The sentence is correct as written. The verb decided can properly be followed by the infinitive construction to crowdsource, and the phrase fits the intended meaning of obtaining ideas from a large group. The other alternatives either misuse the verb form or create an unsuitable prepositional construction.
DIRECTIONS: Read the following passage carefully and answer the questions given below. Certain words/phrases are printed in bold to help you to locate them while answering some of the questions. <br><br><br> A regional research authority began an experimental programme to convert agricultural residue and organic waste into <strong>biofuel</strong>. Instead of allowing a small technical committee to design the project entirely by itself, the authority decided to <strong>crowdsource</strong> proposals from researchers, local enterprises and members of the public. The purpose was not merely to collect a large number of suggestions but to discover approaches that the central committee might otherwise overlook. <br><br> The first phase produced hundreds of submissions. However, the authority did not assume that popularity guaranteed scientific merit. Specialists were appointed to <strong>superintend</strong> a smaller pilot programme and examine the most promising proposals under controlled conditions. During these trials, researchers identified a <strong>microbe</strong> that appeared useful in processing certain forms of organic material. The finding was encouraging but the investigators warned against drawing broad conclusions from a limited trial. <br><br> Another difficulty arose when several sets of experimental information appeared inconsistent. Analysts had to <strong>decode</strong> the technical data before they could determine whether the apparent differences resulted from the biological process itself or from variations in the testing conditions. Consequently, the programme advanced more slowly than several participants had expected. <br><br> The experience demonstrated that wider participation can expand the range of available ideas but cannot replace careful supervision and evaluation. Crowdsourcing widened the field of possible solutions while controlled investigation helped distinguish attractive proposals from workable ones. The authority therefore chose to expand the programme gradually rather than treat an experimental success as conclusive proof.
In the passage, the authority decided to crowdsource proposals primarily in order to:
Explanation: The passage states that the authority sought proposals from researchers, enterprises and the public so that ideas overlooked by a small committee could be considered. Thus crowdsource means obtaining ideas from a large group. The authority did not surrender evaluation or centralize participation; it deliberately broadened participation.

Which of the following can most reasonably be inferred from the passage?
Explanation: The investigators specifically warned against drawing broad conclusions from a limited trial and the authority chose gradual expansion rather than treating an experimental success as conclusive. This shows that preliminary promise was regarded as insufficient without further controlled examination. The remaining alternatives directly contradict the passage.

The word decode as used in the passage is closest in meaning to:
Explanation: In the passage, analysts had to make technical information understandable before interpreting the experimental differences. Decipher therefore best matches decode. Encrypt, scramble and cipher are associated with converting information into coded form or obscuring it while withhold means keeping something back.

Which of the following is opposite in sense to the participatory idea conveyed by crowdsource in the passage?
Explanation: Crowdsourcing distributes participation among a large group and draws ideas or services from that group. Centralize conveys the opposite tendency of concentrating control or activity within a limited centre. Collaborate, solicit, pool and outsource are all associated with or closer to the participatory idea represented by crowdsourcing.

Consider the following statements about the passage: <br><br> I. The authority believed that a larger number of proposals automatically ensured scientific reliability. <br><br> II. A microbe identified during the pilot programme was immediately accepted as conclusive proof of the programme’s overall success. <br><br> III. The authority combined broad participation with controlled evaluation before deciding to expand the programme. <br><br> Which of the statements given above is/are correct?
Explanation: Statement III alone is correct. The passage explicitly distinguishes broad participation from scientific validation and shows that proposals were subjected to controlled evaluation. Statement I is false because popularity was not treated as proof of merit and Statement II is false because the researchers cautioned against treating a limited experimental result as conclusive.
