1. Select the meaning of the underlined word in the following sentence. All volatile liquids should be stored and labeled correctly.

A. Unstable
B. Abnormal
C. Lethal
D. Blended

Correct answer: A

Rationale: In the context of the sentence, 'volatile' means likely to change rapidly and unpredictably or evaporate quickly. When referring to liquids, volatile typically implies that the liquids are unstable and can easily change from liquid to gas. Therefore, the most appropriate meaning of 'volatile' in this sentence is 'unstable.' Choices B, C, and D are incorrect because 'abnormal' and 'lethal' do not capture the essence of rapid change or evaporation associated with volatile liquids, while 'blended' is unrelated to the characteristics of volatile liquids described in the sentence.

2. What is another word for toxin?

A. Impurity
B. Element
C. Remedy
D. Poison

Correct answer: D

Rationale: The correct answer is D, Poison. A toxin is a harmful substance that can cause illness or death, and poison is a synonym commonly used to refer to such substances. Choices A, B, and C are incorrect because impurity refers to something being dirty or unclean, an element is a pure substance that cannot be broken down further, and a remedy is a solution or treatment for a problem, not a harmful substance like a toxin.

3. What term refers to the description of events in the order of their occurrence?

A. Chronology
B. Notation
C. Documentation
D. Helicon

Correct answer: A

Rationale: The correct answer is 'Chronology,' which specifically means the arrangement of events in the order of their occurrence. 'Notation' refers to a system of symbols or signs used to represent information. 'Documentation' is the process of recording information, while 'Helicon' does not relate to the description of events.

4. What does 'Fatal' mean?

A. Resulting in injury
B. Resulting in death
C. Dangerous
D. Treatable

Correct answer: B

Rationale: The correct answer is B: 'Resulting in death.' The term 'Fatal' specifically means resulting in death. Choices A, C, and D are incorrect because 'Fatal' does not refer to resulting in injury, being dangerous, or being treatable.

5. Which of the following sentences uses the correct form of the verb?

A. She was going to the store
B. She was going to the store
C. She has gone to the store
D. She gone to the store

Correct answer: B

Rationale: The correct answer is 'She was going to the store.' This sentence uses the correct form of the past continuous tense, which is appropriate for describing an action in progress in the past. Choice A is the only option that uses the correct verb form. Choice C uses the present perfect tense, which is not suitable for describing a past action in progress. Choice D is incorrect as it lacks the auxiliary verb 'has' in the sentence structure.
