1. What is the meaning of the word 'ideal' as it is used in the first paragraph?

• A. thoughtful
• B. confined
• C. hostile
• D. perfect

Correct answer: D

Rationale: In this context, 'ideal' means perfect. The human body provides a perfect environment for many microbes, as stated in the extract. It is the immune system's role to keep these microbes out or destroy them. The other choices are incorrect: 'thoughtful' does not fit the context of the sentence, 'confined' and 'hostile' are not synonymous with 'ideal' in this context.

2. Add 2/3 + 4/9.

• A. 8/15
• B. 1
• C. 10/9
• D. 1/2

Correct answer: C

Rationale: To add the fractions, first find a common denominator. The least common denominator between 3 and 9 is 9. Convert 2/3 to 6/9 then add 6/9 + 4/9: = 10/9

3. Which of the following is a characteristic of an exothermic reaction?

• A. It absorbs heat
• B. It releases heat
• C. It remains neutral
• D. It requires energy input

Correct answer: B

Rationale: An exothermic reaction is characterized by the release of heat. During an exothermic reaction, energy is released in the form of heat to the surroundings, resulting in a temperature increase. This distinguishes it from endothermic reactions, which absorb heat from the surroundings. Choice A is incorrect because exothermic reactions do not absorb heat; instead, they release heat. Choice C is incorrect as exothermic reactions do not remain neutral; they involve a net release of energy. Choice D is incorrect as exothermic reactions do not require energy input; instead, they release energy.

4. What is the term for the lower surface of a structure?

• A. Inferior
• B. Transverse
• C. Dorsal
• D. Ventral

Correct answer: D

Rationale: The correct answer is 'Ventral' because it specifically refers to the lower surface of a structure. 'Inferior' means below in position, 'Transverse' means situated across something, and 'Dorsal' refers to the upper side or back of a structure, making them incorrect in the context of the lower surface of a structure.

5. What is the CORRECT CONTRACTION for 'will not'?

• A. Won't
• B. Willn't
• C. Wouldn't
• D. Will'nt

Correct answer: A

Rationale: The correct contraction for 'will not' is 'won't'. 'Willn't' (Choice B) is not a standard contraction in English. 'Wouldn't' (Choice C) is the contraction for 'would not,' not 'will not.' 'Will'nt' (Choice D) is not a recognized contraction in English. Therefore, 'won't' is the correct choice as the contraction for 'will not.'
