1. Which of the following substances has the highest density?

• A. Mist
• B. Water
• C. Steam
• D. Ice

Correct answer: B

Rationale: Water has the highest density among the options provided. Density is a measure of mass per unit volume. In this case, water in its liquid form is denser than mist, steam, and ice. Ice has a lower density than water because its crystalline structure causes it to be less dense. Mist and steam are forms of water vapor, which are much less dense than liquid water. Therefore, the correct answer is water (choice B).

2. Which word is NOT GRAMMATICALLY CORRECT? During the time he lived in New York, he worked as a writer, an editor, and a library.

• A. An
• B. Library
• C. As
• D. During

Correct answer: B

Rationale: The word 'library' is incorrect in this context. It should be 'librarian' to be grammatically correct. The other choices ('an,' 'as,' 'during') are all grammatically correct and fit appropriately in the sentence.

3. I am looking forward to ___________ on a vacation next month.

• A. Go
• B. Going
• C. Be going
• D. Going to go

Correct answer: B

Rationale: In this sentence, the correct form is the gerund 'going' after the preposition 'to.' The gerund form is used after prepositions to indicate an action or state. Therefore, 'Going' is the correct choice to complete the sentence. Choice A ('Go') is incorrect because it is not the gerund form required after 'to.' Choice C ('Be going') is incorrect as it is not the standard form used in this context. Choice D ('Going to go') is redundant and unnecessarily wordy.

4. What type of cells are involved in meiosis (sex cells)?

• A. Somatic Cells
• B. Gametes
• C. Zygote
• D. Diploid Cells

Correct answer: B

Rationale: The correct answer is B, Gametes. Gametes are the specialized sex cells involved in meiosis, such as sperm and eggs. Somatic cells (A) are non-reproductive cells found in the body, not involved in meiosis. Zygote (C) is the result of fertilization, formed when gametes unite. Diploid cells (D) have two sets of chromosomes, but in meiosis, gametes are produced through a process of cell division that reduces the chromosome number by half to haploid.

5. The patients are under 'quarantine'. What does this mean?

• A. Confinement away from the general population
• B. A specialist’s care
• C. Experimental drug therapy
• D. Imprisonment in a rehabilitation unit

Correct answer: A

Rationale: The correct answer is A: 'Confinement away from the general population.' Quarantine refers to keeping someone isolated from the general population to prevent the spread of disease. Choice B, 'A specialist’s care,' is incorrect as it refers to medical treatment by a specialist, not isolation. Choice C, 'Experimental drug therapy,' is incorrect as it involves the administration of new drugs for research purposes, not isolation. Choice D, 'Imprisonment in a rehabilitation unit,' is incorrect as it implies being detained in a rehabilitation facility, not isolation for health reasons.
