1. If a party planner assumes 2 bottles of sparkling water per 5 guests, how many bottles must she purchase for a party of 145 guests?

• A. 27
• B. 36
• C. 49
• D. 58

Correct answer: D

Rationale: If the party planner assumes 2 bottles of sparkling water per 5 guests, for a party of 145 guests, she would need ((2/5) x 145) bottles of sparkling water. This calculation results in 58 bottles. Therefore, she must purchase 58 bottles for the party of 145 guests. Choices A, B, and C are incorrect as they do not reflect the correct calculation based on the given assumption.

2. What is the word part placed before a word to change its meaning?

• A. Prefix
• B. Affix
• C. Suffix
• D. Vocab

Correct answer: A

Rationale: A prefix is the correct answer. A prefix is a word part attached at the beginning of a word to modify its root word, changing the definition or grammatical function of the word. Examples of prefixes include "un-" in "unhappy," "re-" in "redo," and "pre-" in "preview." Choice B, "Affix," is incorrect because while a prefix is a type of affix, not all affixes are prefixes. Choice C, "Suffix," is incorrect as a suffix is a word part added at the end of a word to change its meaning. Choice D, "Vocab," is incorrect as it refers to vocabulary or words related to a particular subject rather than a word part placed before a word.

3. Which of the following pH values is most likely for lemon juice?

• A. 3
• B. 5
• C. 7
• D. 9

Correct answer: A

Rationale: Lemon juice is highly acidic with a pH around 2-3, making it more acidic than neutral substances. A pH of 5 is too high for lemon juice, indicating less acidity. Similarly, pH 7 is neutral, and pH 9 would be alkaline, which is not characteristic of lemon juice. Therefore, the correct answer is option A (pH 3).

4. Which gland is responsible for regulating metabolism and calcium levels?

• A. Pituitary gland
• B. Adrenal gland
• C. Thyroid gland
• D. Pineal gland

Correct answer: C

Rationale: The correct answer is the thyroid gland (Choice C). The thyroid gland plays a crucial role in regulating metabolism by producing hormones like thyroxine, which control the body's metabolic rate. It also helps in controlling calcium levels in the blood through the release of calcitonin. The pituitary gland (Choice A) is known as the 'master gland' as it controls other glands but is not primarily responsible for regulating metabolism and calcium levels. The adrenal gland (Choice B) produces hormones like cortisol and adrenaline, which are involved in the stress response and metabolism, but they do not specifically regulate calcium levels. The pineal gland (Choice D) mainly produces melatonin, a hormone that helps in regulating sleep-wake cycles and has no direct role in metabolism or calcium level regulation.

5. Which of the following statements is an opinion?

• A. The connection between sleep and weight should be explored.
• B. Many young children average only eight hours of sleep a night.
• C. People who sleep less are more likely to be obese.
• D. Researchers in New Zealand studied almost 600 children.

Correct answer: A

Rationale: The statement that the connection between sleep and weight should be explored reflects a personal viewpoint rather than an objective fact. It indicates a belief that further research is warranted to understand this relationship better, making it an opinion and distinguishing it from the other factual statements presented in the passage.
