This is the Vocab24 daily quiz of 31 July 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.
STOCHASTIC
Explanation: Probabilistic best expresses the meaning of stochastic, which refers to something governed by randomness or probability. Systematic, deterministic, and predictable suggest an orderly or certain process and are therefore contrary to the precise meaning of the target word.
Out of the given alternatives select the alternative which best expresses the meaning of given word.
CARAPACE
Explanation: A carapace is a hard protective shell covering the back of animals such as turtles, crabs, and certain insects; therefore, armour is the closest synonym. Exposure, softness, and vulnerability indicate the absence of protection and function as opposites rather than synonyms.
Out of the given alternatives select the alternative which best expresses the meaning of given word.
TROUBLESHOOT
Explanation: Troubleshoot means to identify the cause of a problem and take steps to solve it, so diagnose is the most appropriate synonym. Complicate, disrupt, ignore, and damage either worsen a problem or leave it unresolved and therefore do not convey the intended meaning.
Out of the given alternatives select the alternative which best expresses the meaning of given word.
ZODIACAL
Explanation: Zodiacal means relating to the zodiac or the twelve astrological signs, making astrological the most accurate synonym. Terrestrial, earthly, and noncelestial refer to matters connected with the earth and are opposite in sense to the celestial association of the target word.
Out of the given alternatives select the alternative which best expresses the meaning of given word.
ATOMIZE
Explanation: Atomize means to break a substance into extremely small particles or a fine spray, whereas consolidate means to combine separate parts into a unified whole. Fragment, pulverize, and disintegrate all involve breaking something apart and are therefore similar rather than opposite in meaning.
Out of the given alternatives select the alternative which best expresses the meaning of given word.
MOONLIGHT
Explanation: Moonlight is the natural light reflected from the moon, while darkness denotes the absence of light and is therefore its clearest antonym. Lunar glow, moonbeam, and moonshine are all closely associated with light from the moon and cannot serve as opposites.
Out of the given alternatives select the alternative which best expresses the meaning of given word.
CHRYSALIS
Explanation: A chrysalis is the protected developmental stage in which a caterpillar transforms into a butterfly or moth, whereas maturity represents the fully developed state. Pupa, cocoon, and pupal case are closely related to the transitional stage and therefore function as synonyms or associated terms.
Out of the given alternatives select the alternative which best expresses the meaning of given word.
BENTHIC
Explanation: Benthic refers to organisms or conditions associated with the bottom of a sea, lake, or other body of water, while pelagic refers to the open-water or surface regions. Demersal, bottom-dwelling, seabed, and deep-water remain closely connected with the lower aquatic zone.
Out of given alternatives, choose the word which can be substituted for the given words/ sentence.
The branch of medicine concerned with the study, diagnosis, and treatment of cancer
Explanation: Oncology is the branch of medicine dealing specifically with the study, diagnosis, and treatment of cancer. Chrysalis is a developmental stage, carapace is a protective shell, vellum is a writing material, and moonlight is light reflected from the moon.
Out of given alternatives, choose the word which can be substituted for the given words/ sentence.
Fine-quality parchment traditionally made from animal skin and used for writing or printing
Explanation: Vellum precisely denotes fine-quality parchment made from animal skin and traditionally used for writing or printing. A carapace is an animal shell, a chrysalis is a pupal stage, moonlight is lunar illumination, and oncology is a medical discipline.
Out of given alternatives, choose the word which can be substituted for the given words/ sentence.
To identify and solve faults in a machine, system, or process
Explanation: Troubleshoot means to examine a machine, system, or process in order to identify and solve a problem. Atomize means to reduce something to tiny particles, while stochastic and zodiacal are adjectives, and moonlight ordinarily refers to reflected lunar light.
Out of given alternatives, choose the word which can be substituted for the given words/ sentence.
A hard protective shell covering the back of certain animals
Explanation: Carapace is the exact word for the hard protective shell found on animals such as turtles, crabs, and certain insects. A chrysalis is a transformation stage, vellum is parchment, benthos refers to organisms living at the bottom of water, and oncology is related to cancer medicine.
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 the movement of prices was governed by probability rather than certainty, the analysts adopted a ______ model.
Explanation: A model governed by probability and randomness is described as stochastic. Deterministic, systematic, predictable, and certain suggest fixed, orderly, or reliably foreseeable outcomes and therefore contradict the context of uncertainty.
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 machine was designed to ______ the liquid so that it emerged as an extremely fine spray.
Explanation: Atomize means to reduce a liquid into very small particles or a fine spray, which fits the stated function of the machine. Consolidate, assemble, unify, and combine all indicate bringing separate elements together rather than dispersing them.
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 marine survey concentrated on ______ organisms living along the muddy floor of the lake.
Explanation: Organisms that live at the bottom of a lake or sea are described as benthic. Pelagic and surface-dwelling refer to open-water or upper-water regions, while aerial and terrestrial relate to the air and land respectively.
Out of given alternatives select the option which best expresses the meaning of given idiom/ phrase.
Shoot down the trouble most appropriately suggests:
Explanation: The phrase suggests identifying a difficulty and eliminating it by finding an effective solution, which corresponds to the meaning of troubleshoot. The other alternatives involve damaging, ignoring, or worsening a problem rather than solving it.
Out of given alternatives select the option which best expresses the meaning of given idiom/ phrase.
As tiny as atoms conveys the idea of:
Explanation: The phrase as tiny as atoms expresses the idea of reducing a substance into extremely small particles, which reflects the meaning of atomize. The other choices concern consolidation, protection, or development and do not convey fragmentation into minute particles.
Out of given alternatives select the option which best expresses the meaning of given idiom/ phrase.
Close to the bottom in an aquatic context means:
Explanation: In an aquatic context, close to the bottom describes a benthic position, meaning living on or relating to the floor of a sea, lake, or other body of water. The other options refer to pelagic, terrestrial, or surface-dwelling conditions and therefore do not fit.
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 asked to troubleshoots the faulty network before the system was restarted.
Explanation: After the infinitive marker to, the base form of the verb must be used; therefore, troubleshoot the faulty network is correct. Troubleshooting is a participial form, troubleshot is the past form, and the original phrase incorrectly uses the singular present form troubleshoots.
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 laboratory instrument atomizes the liquid into a fine mist before the analysis begins.
Explanation: The sentence is grammatically correct because the singular subject instrument appropriately takes the singular present-tense verb atomizes. The remaining alternatives either create subject-verb disagreement, introduce an unsuitable tense, or produce an incomplete 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.
Many benthic organisms lives on the muddy floor of the ocean.
Explanation: The plural subject organisms requires the plural verb live, making live on the muddy floor the correct replacement. Has lived and is living incorrectly use singular auxiliary verbs, while the original phrase contains a subject-verb agreement error.
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 coastal research institute initiated an ambitious project to examine the effect of industrial activity on a deep lake. The investigators recognised that a purely deterministic model could not account for every variation in temperature, sediment, and biological movement. They therefore developed a <strong> stochastic </strong> framework capable of incorporating uncertain changes without presenting them as guaranteed outcomes. <br><br> Special attention was given to <strong> benthic </strong> organisms because these creatures inhabited the muddy floor where pollutants were most likely to accumulate. A remotely operated device collected samples and <strong> atomized </strong> selected liquids into a fine mist for laboratory examination. When the device began producing irregular results, the technical team was required to <strong> troubleshoot </strong> both its mechanical components and its data-processing system. <br><br> The project also had a historical dimension. Researchers studied an old navigational record preserved on <strong> vellum </strong>. The document contained several <strong>zodiacal</strong> diagrams that early sailors had apparently used while observing the night sky. Although the diagrams were not treated as modern scientific evidence, they helped scholars understand how celestial observations had influenced navigation. <br><br> The investigation ultimately demonstrated that reliable scientific judgment does not require researchers to deny uncertainty. Instead, uncertainty must be measured, examined, and communicated accurately. The team concluded that a model becomes misleading not merely when it contains uncertainty, but when it conceals the limits of its own predictions.
In the passage, the word stochastic most nearly means:
Explanation: The passage contrasts the stochastic framework with a deterministic model and states that it incorporates uncertain changes without treating them as guaranteed outcomes. Therefore, governed partly by probability is the most accurate contextual meaning, while the other options imply certainty, rigidity, or an unrelated historical basis.

Which of the following can be inferred about the old zodiacal diagrams?
Explanation: The passage explicitly states that the zodiacal diagrams were not treated as modern scientific evidence but helped scholars understand the influence of celestial observations on navigation. Thus, their importance was historical and interpretative rather than technological or scientifically conclusive.

Which statement is true according to the passage?
Explanation: The passage concludes that uncertainty should be measured, examined, and communicated accurately and that models become misleading when they conceal the limits of their predictions. The remaining statements directly contradict the passage because the deterministic model was insufficient, the diagrams were not modern proof, the equipment was examined rather than ignored, and the study focused on bottom-dwelling organisms.
