This is the Vocab24 daily quiz of 4 September 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.
BROADCAST
Explanation: Disseminate is the best synonym of broadcast because both can mean spreading or transmitting information to a large audience. Withhold, restrict, and conceal express the opposite idea because they involve preventing information from being communicated or made widely available.
Out of the given alternatives select the alternative which best expresses the meaning of given word.
GLUTINOUS
Explanation: Viscous is the closest synonym of glutinous, which describes something having a sticky or glue-like consistency. Fluid, loose, and dry indicate qualities that contrast with stickiness or adhesiveness and therefore cannot express the intended meaning.
Out of the given alternatives select the alternative which best expresses the meaning of given word.
INSUFFERABLE
Explanation: Unbearable precisely expresses the meaning of insufferable, which refers to something extremely unpleasant or difficult to tolerate. Acceptable, endurable, and tolerable suggest that something can be endured and therefore function as opposites rather than synonyms.
Out of the given alternatives select the alternative which best expresses the meaning of given word.
RESCHEDULE
Explanation: Rearrange is the most appropriate synonym because reschedule means arranging an event or activity for a different date or time. Confirm, retain, and maintain generally imply keeping an existing arrangement rather than altering its scheduled timing.
Out of the given alternatives select the word opposite in meaning to the given word.
POISONOUS
Explanation: Harmless is the clearest antonym of poisonous. Something poisonous may cause illness, injury, or death whereas something harmless does not cause such damage. Noxious, toxic, and deadly reinforce rather than oppose the meaning of poisonous.
Out of the given alternatives select the word opposite in meaning to the given word.
REFRIGERATE
Explanation: Warm is an antonym of refrigerate, which means making or keeping something cold, particularly for preservation. Chill and cool directly support the meaning of refrigeration while preserve represents one of its common purposes rather than its opposite.
Out of the given alternatives select the word opposite in meaning to the given word.
PHOTOSYNTHESIS
Explanation: Respiration is listed as an opposite of photosynthesis. Photosynthesis refers to the process by which green plants use sunlight to make food from carbon dioxide and water. Photoassimilation, phototrophy, and carbon assimilation are associated with the same general process rather than its opposite.
Out of the given alternatives select the word opposite in meaning to the given word.
SUPERSONIC
Explanation: Subsonic is the appropriate antonym because supersonic describes motion at a speed greater than the speed of sound. Faster-than-sound directly expresses its meaning while high-speed and transonic are related speed terms rather than suitable opposites.
Out of given alternatives, choose the word which can be substituted for the given words/ sentence.
The process through which green plants use sunlight to make food from carbon dioxide and water.
Explanation: Photosynthesis precisely substitutes the given definition because it is the process by which green plants use sunlight to make food from carbon dioxide and water. Broadcast concerns transmission, refrigerate concerns cooling and reschedule concerns changing the time of an event.
Out of given alternatives, choose the word which can be substituted for the given words/ sentence.
A small electronic device containing the central processing unit of a computer on a single integrated circuit.
Explanation: Microprocessor is the exact one-word substitution because it refers to the small electronic device that contains a computer’s central processing unit on a single integrated circuit. The remaining alternatives refer respectively to speed, a disease, and the transmission of information.
Out of given alternatives, choose the word which can be substituted for the given words/ sentence.
To transmit a programme or information through radio, television, or another communication system.
Explanation: Broadcast precisely means transmitting a programme or information through radio, television, or other communication systems. Refrigerate means to keep cold, reschedule means to arrange for a different time and photosynthesis is a biological process in green plants.
Out of given alternatives, choose the word which can be substituted for the given words/ sentence.
Having a sticky or glue-like consistency.
Explanation: Glutinous is the correct substitution because it describes something sticky, gummy, viscous, or glue-like in consistency. Poisonous concerns harmful substances, insufferable concerns something intolerable and supersonic concerns movement faster than sound.
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.
The forest officer warned the visitors not to consume unfamiliar mushrooms because some species could be ________.
Explanation: Poisonous best fits the context because it describes something containing or producing a substance capable of causing illness, injury, or death. The warning against consuming unfamiliar mushrooms directly concerns possible toxicity. The remaining options refer to stickiness, speed, cooling, or changes in scheduling.
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.
The combination of extreme heat, poor ventilation and constant noise made working conditions almost ________ for the staff.
Explanation: Insufferable is appropriate because the sentence describes conditions that are extremely unpleasant and difficult to tolerate. Glutinous refers to a sticky consistency, supersonic concerns speed, refrigerated concerns cooling and poisonous refers to something capable of causing harmful toxic effects.
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.
Since several delegates could not arrive on the original date, the organisers decided to ________ the conference.
Explanation: Reschedule correctly completes the sentence because the delegates’ inability to arrive on the original date requires the conference to be arranged for another time or date. Broadcast and refrigerate express unrelated actions while photosynthesis and glutinous do not function appropriately in this grammatical context.
Out of given alternatives select the option which best expresses the meaning of given idiom/ phrase.
Faster than the speed of sound most appropriately corresponds to:
Explanation: Supersonic means moving at a speed greater than the speed of sound, so it precisely corresponds to the given phrase. Microprocessor is an electronic device, refrigerated concerns cooling and glutinous describes a sticky consistency.
Out of given alternatives select the option which best expresses the meaning of given idiom/ phrase.
The phrase sticky like glue most appropriately conveys the meaning of:
Explanation: Glutinous describes a substance having a sticky or glue-like consistency. The comparison with glue therefore directly points to this adjective. Insufferable describes something intolerable, poisonous refers to harmful toxicity and supersonic describes movement faster than sound.
Out of given alternatives select the option which best expresses the meaning of given idiom/ phrase.
The phrase spread information broadly to many people at once is most closely associated with:
Explanation: Broadcast is the correct choice because it involves transmitting or spreading information through communication systems to a broad audience. Reschedule changes timing, refrigerate keeps something cold and microprocessor refers to an electronic processing device.
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 committee decided to rescheduled the meeting after several members reported that they would be unavailable.
Explanation: After decided to, the base form of the verb is required; therefore, reschedule the meeting is grammatically correct. Rescheduled cannot follow the infinitive marker to in this construction, while rescheduling and reschedules are also incompatible with the required infinitive form.
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 opened packet of milk should be refrigerating immediately to prevent unnecessary deterioration.
Explanation: The sentence is passive because the milk receives the action. After the modal construction should be, the past participle refrigerated is required. Refrigerate would require an active construction while refrigerates is a finite present-tense form and refrigerating incorrectly creates a progressive form.
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.
Engineers reported that the experimental aircraft was travelling at a supersonic speed during the test.
Explanation: The original phrase is grammatically correct. The singular subject aircraft agrees with was, and travelling appropriately forms the past continuous tense. Supersonic is correctly used adjectivally to describe a speed greater than the speed of sound.
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> A national science exhibition had been planned as a public demonstration of how familiar scientific processes and technologies influence everyday life. However, an <strong>insufferable</strong> spell of heat forced the organisers to <strong>reschedule</strong> several outdoor sessions. Instead of cancelling the programme, they shifted sensitive exhibits indoors and used a digital communication system to <strong>broadcast</strong> selected demonstrations to participants who could not enter the main hall. <br><br> One section explained <strong>photosynthesis</strong> by showing how green plants use sunlight in producing food. Nearby, another exhibit demonstrated how a <strong>microprocessor</strong> could perform large numbers of calculations while controlling different electronic operations. The organisers deliberately placed these displays together to show that processes occurring in nature and processes performed by machines may differ fundamentally even when both appear complex to an observer. <br><br> Food safety formed another part of the exhibition. Visitors were advised to <strong>refrigerate</strong> certain items after opening them and were cautioned against eating unfamiliar wild mushrooms because some might be <strong>poisonous</strong>. A demonstration involving cooked rice also drew attention to its soft, <strong>glutinous</strong> texture. The purpose was not merely to present isolated definitions but to show why precise vocabulary matters when scientific information is communicated to the public. <br><br> The final presentation dealt with a <strong>supersonic</strong> aircraft. Instead of treating high speed as a vague description, the presenter emphasised that the term applies specifically to movement faster than the speed of sound. By the end of the exhibition, the organisers had demonstrated that technical words are most useful when their meanings are understood precisely rather than approximately.
Which of the following can most reasonably be inferred about the organisers of the exhibition?
Explanation: The passage repeatedly emphasises precise vocabulary and concludes that technical words are most useful when their meanings are understood accurately. Option (a) contradicts this purpose, option (c) ignores the stated fundamental difference between natural and machine processes and option (d) is incorrect because the programme was rescheduled rather than cancelled.

Which of the following statements is correct according to the passage?
Explanation: The final presentation explicitly explains that supersonic applies to movement faster than the speed of sound. The other statements contradict the passage: photosynthesis is presented as a natural plant process, the programme was rescheduled rather than cancelled, unfamiliar mushrooms were treated as potentially poisonous and precise definitions were regarded as important.

Which of the following is the most appropriate opposite of glutinous in the context of the passage?
Explanation: In the passage, glutinous describes the sticky texture of cooked rice. Dry provides the clearest opposite to that sticky consistency. Gummy, sticky, and adhesive all reinforce the meaning of glutinous rather than contrast with it.

Which word is closest in meaning to insufferable as used in the first paragraph?
Explanation: The extreme heat was sufficiently unpleasant to force changes in the programme, so unbearable best expresses the contextual meaning of insufferable. Acceptable, bearable, and endurable all suggest that the condition can be tolerated and therefore convey the opposite idea.

In the context of the passage, the word refrigerate most nearly means:
Explanation: In the food-safety section, visitors are advised to refrigerate certain items after opening them. The contextual meaning is therefore to make or keep the items cold, especially for preservation. The other alternatives correspond to heating, broadcasting, or rescheduling and do not fit the food-safety context.
