This is the Vocab24 daily quiz of 19 August 2026, the same 30 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.
STRIATED
Explanation: Banded best expresses the meaning of striated, which describes something marked with narrow parallel lines, grooves, or bands. Smooth, uniform, and unmarked convey the absence of such visible markings and therefore represent contrasting rather than synonymous ideas.
Out of the given alternatives select the alternative which best expresses the meaning of given word.
RETREAT
Explanation: Withdraw is the closest synonym of retreat because both refer to moving back from a difficult, dangerous, or unfavourable situation. Proceed, approach, and confront imply movement towards or engagement with a situation rather than movement away from it.
Out of the given alternatives select the alternative which best expresses the meaning of given word.
PROBLEMATIC
Explanation: Questionable is an appropriate synonym of problematic because something problematic may cause difficulties or raise concerns. Manageable, straightforward, and simple suggest relative ease or absence of difficulty and therefore do not convey the intended meaning.
Out of the given alternatives select the alternative which best expresses the meaning of given word.
NETWORK
Explanation: Framework most closely expresses the meaning of network in the sense of an organised and connected system of people, things, roads, or devices. Isolation, detachment, and separation emphasise disconnection and are therefore contrary to the central idea of a network.
Out of the given alternatives select the word opposite in meaning to the given word.
BOUNDLESS
Explanation: Finite is the appropriate antonym of boundless because it indicates that something has definite limits, whereas boundless means having no limits or boundaries. Endless, unbounded, and infinite reinforce rather than oppose the meaning of the given word.
Out of the given alternatives select the word opposite in meaning to the given word.
DRIFT
Explanation: Halt is the best opposite of drift. To drift is to move slowly without a definite direction, whereas to halt is to stop movement. Glide, roam, and wander all retain the idea of movement and are therefore unsuitable as antonyms.
Out of the given alternatives select the word opposite in meaning to the given word.
CRUSH
Explanation: Preserve is the strongest antonym of crush because crushing involves damaging, breaking, or deforming something through pressure, while preserving involves keeping it protected from damage. Mash, compress, and pulverize all convey actions closely associated with crushing.
Out of the given alternatives select the word opposite in meaning to the given word.
MARSH
Explanation: Desert is the best opposite of marsh. A marsh is characteristically low and wet land supporting soft vegetation, whereas a desert represents dry land. Wetland, bog, and fen are closely related to the meaning of marsh and therefore cannot function as antonyms.
Out of given alternatives, choose the word which can be substituted for the given words/ sentence.
A soft and porous material capable of absorbing and holding liquid.
Explanation: Sponge precisely substitutes the given definition because it refers to a soft, porous material or organism capable of absorbing and retaining liquid. A marsh is wet land, a document is a record and a network is a connected system; therefore, none of them fits the definition.
Out of given alternatives, choose the word which can be substituted for the given words/ sentence.
An area of low, wet land mainly covered with grasses and other soft vegetation.
Explanation: Marsh is the correct one-word substitution because it denotes low, wet land generally covered with grasses and similar vegetation. A network is a connected system, a sponge is an absorbent material and a document is a written or electronic record.
Out of given alternatives, choose the word which can be substituted for the given words/ sentence.
A written, printed, or electronic record that provides information or evidence.
Explanation: Document directly corresponds to a written, printed, or electronic record providing information or evidence. The remaining choices refer respectively to a connected system, wet land and an absorbent material and therefore cannot substitute the definition.
Out of given alternatives, choose the word which can be substituted for the given words/ sentence.
A connected system of people, things, roads, or devices that work or communicate together.
Explanation: Network correctly represents a connected system in which different people, objects, roads, or devices are linked and operate or communicate together. Document, marsh, and sponge describe entirely different concepts and do not contain the essential idea of systematic connection.
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.
Because several important records were unavailable, the committee found the conclusions of the inquiry increasingly ________.
Explanation: Problematic fits because the absence of important records creates difficulties in accepting or establishing reliable conclusions. Manageable suggests that the difficulty can readily be handled, while boundless refers to absence of limits and striated refers to visible parallel markings.
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.
With no one controlling the small boat, it began to ________ away from the shore.
Explanation: Drift is correct because the boat is moving slowly without a definite direction or active control. Retreat ordinarily implies deliberate withdrawal, crush means to damage through pressure and document means to record information or evidence.
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.
Even after repeated difficulties, the researcher displayed ________ enthusiasm for completing the investigation.
Explanation: Boundless appropriately modifies enthusiasm and conveys enthusiasm without apparent limits. Finite would indicate limitation, problematic would describe something causing difficulty and striated refers to something marked by parallel bands or grooves.
Out of given alternatives select the option which best expresses the meaning of given idiom/ phrase.
In the expression the boat began to drift away, the phrase drift away most nearly means:
Explanation: Drift away means to move slowly without a definite direction, often because of the influence of air or water. It does not indicate settling, deliberate rapid movement or confrontation with a difficult situation.
Out of given alternatives select the option which best expresses the meaning of given idiom/ phrase.
The phrase without boundaries most nearly conveys the idea of being:
Explanation: Without boundaries means having no limits and therefore corresponds to the idea expressed by boundless. Restricted, finite, and bounded all imply the existence of limits and consequently express the opposite idea.
Out of given alternatives select the option which best expresses the meaning of given idiom/ phrase.
In the expression a sponge soaks up water quickly, the phrase soaks up means:
Explanation: Soaks up means absorbs and retains liquid, which is the characteristic function associated with a sponge. Repelling liquid and remaining impermeable express the opposite property, while damaging something by pressure relates to crushing rather than absorption.
Out of given alternatives select the word which is correctly spelt.
Select the correctly spelt word.
Explanation: Boundless is the correct spelling. It is formed from bound with the suffix -less, conveying the idea of being without boundaries or limits. The other alternatives contain incorrect omission, substitution, or duplication of letters.
Out of given alternatives select the word which is correctly spelt.
Select the correctly spelt word.
Explanation: Problematic is the correctly spelt form. The alternatives incorrectly introduce an additional consonant or an unnecessary final letter. In competitive examinations, such minor alterations are commonly used to test precise recognition of standard spelling.
Out of given alternatives select the word which is correctly spelt.
Select the correctly spelt word.
Explanation: Striated is the correct spelling of the adjective describing a surface marked with parallel lines, bands, or grooves. The remaining alternatives alter the vowel sequence or incorrectly double or replace consonants.
Out of given alternatives select the word which is correctly spelt.
Select the correctly spelt word.
Explanation: Network is the standard correct spelling. Netwrok reverses letters, while Nettwork and Netwoork unnecessarily duplicate letters. The correct word refers to a connected system whose separate elements work or communicate together.
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 striated surface of the rock were visible beneath the dust.
Explanation: Was visible is required because the grammatical subject is the singular noun surface, not the plural-looking phrase that follows it. Therefore, the singular verb was must agree with surface. The other alternatives either create subject-verb disagreement or unnecessarily alter the tense.
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.
After losing their position, the soldiers were forced retreat from the area.
Explanation: The correct construction is were forced to retreat because the passive structure be forced is followed by the infinitive to + verb. Were forced retreat omits the required infinitive marker, while the other alternatives do not produce the intended grammatical or logical construction.
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 lack of reliable data proved problematic for the researchers.
Explanation: The sentence is grammatically correct as written. Proved functions as a linking verb and is appropriately followed by the adjective problematic. Problematically is an adverb and does not fit this construction, while the other alternatives contain errors of verb form or agreement.
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> After several days of heavy rain, a team of environmental researchers entered a <strong> marsh </strong> near the river to <strong> document </strong> changes in the landscape. A previously established <strong> network </strong> of narrow paths and observation points allowed them to examine different sections without unnecessarily disturbing the vegetation. At first, the work appeared manageable, but a damaged footbridge made the southern route increasingly <strong> problematic </strong>. <br><br> Rather than <strong> retreat </strong> and abandon the survey, the researchers divided into smaller groups and approached the observation points from safer directions. At one location, receding water had exposed a <strong> striated </strong> rock surface. Its parallel bands made it easy to distinguish from the smoother stones surrounding it. In a shallow pool nearby, fallen leaves and light pieces of vegetation began to <strong> drift </strong> slowly across the water. <br><br> The team leader repeatedly warned the researchers not to crush delicate plants while moving between observation points. A <strong> sponge </strong> was also kept with the equipment so that moisture could be absorbed from instruments before observations were recorded. Despite the inconvenience caused by the damaged bridge, one junior researcher displayed <strong>boundless</strong> enthusiasm and continued examining each accessible section carefully. <br><br> By the end of the survey, the researchers had prepared a detailed document containing observations from every accessible station. They concluded that individual observations became substantially more useful when connected through the wider network of monitoring points.
The word problematic in the passage most nearly means:
Explanation: In the passage, the damaged footbridge makes the southern route difficult to use, so problematic means causing difficulties or presenting a problem. Easy to manage expresses a contrasting idea, while isolated and marked with parallel bands relate to different concepts and do not fit the context.

What can most reasonably be inferred about the importance of the network of observation points?
Explanation: The passage concludes that observations became more useful when they were connected through the wider network of monitoring points. Therefore, the network helped integrate information collected at different locations. The other options contradict the passage by suggesting restriction, complete independence from the bridge, or isolation of observations.

Which of the following is the most appropriate antonym of boundless as used in the passage?
Explanation: Boundless enthusiasm means enthusiasm without apparent limits, so limited is the most appropriate antonym. Endless, infinite, and unbounded all reinforce the sense of having no limits and therefore function as synonyms rather than opposites.

Consider the following statements with reference to the passage: <br><br> I. A damaged footbridge made one part of the survey difficult. <br><br> II. The researchers immediately retreated and abandoned the survey. <br><br> III. Parallel bands distinguished the striated rock from smoother stones. <br><br> Which of the statements given above are true?
Explanation: Statements I and III are correct. The damaged footbridge made the southern route problematic, and the striated rock was identified by its parallel bands. Statement II is incorrect because the researchers did not retreat and abandon the survey; instead, they divided into smaller groups and used safer approaches.
