1. Which of the following is the best example of a hypothesis?

• A. Dogs like treats
• B. Red is the best color
• C. If I eat 100 donuts, then I will feel sick
• D. If a plant is exposed to red light, then it will show less growth than natural light

Correct answer: D

Rationale: Option D is the best example of a hypothesis because it presents a clear cause-and-effect relationship that can be tested through experimentation. It follows the format of 'If [cause], then [effect]' which is characteristic of a hypothesis in scientific research. The statement is specific, testable, and does not rely on personal opinions or biases, making it a strong and valid hypothesis. Choices A, B, and C do not follow the structure of a hypothesis as they lack the cause-and-effect relationship that can be tested through experimentation. They are more like statements or opinions rather than hypotheses.

2. Choose the meaning of the word 'contusions' in the following sentence: 'Contusions or scratches may be treated on-site.'

• A. Breaks
• B. Disorientation
• C. Bruises
• D. Abrasions

Correct answer: C

Rationale: The correct answer is C: 'Bruises.' In the context of the sentence provided, 'contusions' refers to injuries that cause discoloration or bruising of the skin without breaking the skin. The word 'contusions' is synonymous with bruises, not breaks (choice A), disorientation (choice B), or abrasions (choice D). Therefore, in the sentence, contusions or scratches are mentioned as potential injuries that may require treatment on-site.

3. What is the result of adding 12 1/21 and 3 1/3?

• A. 15 8/21
• B. 16 5/24
• C. 15
• D. 14

Correct answer: A

Rationale: To add 12 1/21 and 3 1/3, first add the whole numbers: 12 + 3 = 15. Then, add the fractions: 1/21 + 1/3. To find a common denominator, multiply 21 by 3 to get 63. Convert 1/21 to an equivalent fraction with a denominator of 63 by multiplying the numerator and denominator by 3, resulting in 3/63. Now add 3/63 (equivalent to 1/21) and 21/63 (equivalent to 1/3) to get 24/63. Simplifying 24/63 gives 8/21. Therefore, the sum is 15 8/21. Choices B, C, and D are incorrect because they do not result from the correct addition of the given numbers and fractions.

4. If x=11, solve (x+44)/2x.

• A. 33
• B. 2.5
• C. 13
• D. 55/22

Correct answer: B

Rationale: Given x=11, substitute into the expression: (11 + 44) / (2*11) = 55 / 22 = 2.5. Therefore, the correct answer is 2.5. Choice A (33) is incorrect as it does not represent the correct calculation. Choice C (13) is incorrect as it is not the result of the expression. Choice D (55/22) is incorrect as it is the same as the simplified form of the expression, not the answer to the calculation.

5. What is the meaning of verified?

• A. Belittled
• B. Confirmed
• C. Anecdotal
• D. Implicit

Correct answer: B

Rationale: Verified means confirmed or proven to be true. When something is verified, it has been established as factual or accurate through thorough examination or evidence. It is the opposite of belittled, anecdotal, or implicit, as those terms do not convey the sense of confirmation or validation that verified does.
