1. Select the meaning of the underlined word in the following sentence. The chemicals in plastic containers may be deleterious to children’s health.

A. Harmful
B. Deleting
C. Delightful
D. Inoffensive

Correct answer: A

Rationale: The word 'deleterious' means causing harm or damage. In this context, the sentence implies that the chemicals in plastic containers can be harmful to children's health. Therefore, the correct meaning of the underlined word is 'harmful,' making option A the most suitable choice. Option B 'Deleting' is incorrect because it refers to removing or erasing, which does not fit the context. Option C 'Delightful' is incorrect as it means causing great pleasure or delight, the opposite of the intended meaning. Option D 'Inoffensive' is incorrect as it means not causing any harm or annoyance, which is contrary to the negative impact described in the sentence.

2. What does the word Quarantine mean?

A. Isolation
B. Confinement away from the general population
C. Treatment
D. Exposure

Correct answer: B

Rationale: The correct answer is B: 'Confinement away from the general population.' Quarantine is the practice of isolating individuals who may have been exposed to a contagious disease but are not yet ill. This isolation helps prevent the potential spread of the disease. Choice A, 'Isolation,' is partially correct but does not capture the specific aspect of separation from the general population. Choice C, 'Treatment,' is incorrect as quarantine does not involve providing medical care but rather focusing on preventing transmission. Choice D, 'Exposure,' is also incorrect as quarantine is about separating potentially exposed individuals, not intentionally exposing them.

3. Choose the word or phrase that best indicates the meaning of the 'quoted' word. 'Rational' means:

A. Angry
B. Reason
C. Rodent
D. Proportion

Correct answer: B

Rationale: The correct answer is 'B: Reason.' 'Rational' means based on reason or logic. Choice A, 'Angry,' is incorrect as it does not relate to the meaning of 'rational.' Choice C, 'Rodent,' is a completely unrelated term. Choice D, 'Proportion,' also does not capture the meaning of 'rational,' which is about being logical or reasonable.

4. What does Ominous mean?

A. Insignificant
B. Significantly important and dangerous
C. Trivial
D. Harmless

Correct answer: B

Rationale: Ominous means giving the impression that something bad or unpleasant is going to happen; threatening; inauspicious. This choice is correct as it accurately reflects the meaning of the term 'Ominous.' Choices A, C, and D are incorrect because they all suggest a lack of importance, danger, or threat, which is opposite to the actual meaning of 'Ominous.'

5. The plastic surgery improved the _______ of her face.

A. Bearing
B. Serenity
C. Contour
D. Cataract

Correct answer: C

Rationale: The correct answer is 'Contour.' In the context of the sentence, 'contour' refers to the shape or outline of her face, which is typically altered or enhanced through plastic surgery. 'Bearing' refers to behavior or posture, not the physical appearance of the face. 'Serenity' means calmness and peacefulness, which is not relevant in the context of plastic surgery improving the appearance of the face. 'Cataract' is a medical condition affecting the eye and is completely unrelated to the context of plastic surgery improving facial appearance.
