1. What is the pH of a neutral solution?

• A. 7
• B. 0
• C. 14
• D. 4

Correct answer: A

Rationale: The correct answer is A: 7. A neutral solution has a pH of 7. In the pH scale, values below 7 are acidic, 7 is neutral, and values above 7 are basic. Therefore, a solution with a pH of 7 is considered neutral as it is neither acidic nor basic. Choices B, C, and D are incorrect because a pH of 0 indicates a strong acid, a pH of 14 indicates a strong base, and a pH of 4 indicates an acidic solution. None of these values represent a neutral solution.

2. A die is rolled. What is the probability of getting a 5?

• A. 50%
• B. 20%
• C. 16.60%
• D. 83.30%

Correct answer: C

Rationale: The correct answer is C (16.60%). When rolling a standard 6-sided die, the probability of getting a 5 is 1/6 or approximately 16.6%. Choice A (50%) is incorrect as it represents the probability of getting a specific number on a coin flip, not a die roll. Choice B (20%) is incorrect as it does not reflect the probability of rolling a 5 on a standard die. Choice D (83.30%) is incorrect as it is the complement of the probability of rolling a 5, which is not asked in the question.

3. Which word is not spelled correctly in the context of the following sentence? The pharmacist seemed to disagree with the prescription designated by the physician.

• A. pharmacist
• B. prescription
• C. designated
• D. physician

Correct answer: B

Rationale: The word 'prescription' in the sentence is misspelled as 'proscription.' A prescription is a written order for medication or treatment provided by a healthcare professional, while a proscription means a forbidding or prohibition. The other choices (A, C, D) are all correctly spelled in the context of the sentence.

4. When a die is rolled, what is the probability of rolling an odd number?

• A. 16.67%
• B. 33.33%
• C. 75%
• D. 50%

Correct answer: D

Rationale: When a die is rolled, there are 3 odd numbers (1, 3, 5) out of a total of 6 possible outcomes. The probability of rolling an odd number is calculated by dividing the number of favorable outcomes (3) by the total number of outcomes (6), resulting in a probability of 3/6 or 50%. Therefore, the correct answer is D. Choices A, B, and C are incorrect because they do not reflect the correct probability calculation for rolling an odd number on a standard six-sided die.

5. Why is the nucleus important in a cell?

• A. It stores the DNA
• B. It supports the cell
• C. It makes protein
• D. It makes energy out of food

Correct answer: A

Rationale: The nucleus is important in a cell because it stores the DNA, which contains the genetic information necessary for the cell's function and replication. This genetic material controls the cell's activities and characteristics. Choices B, C, and D are incorrect because supporting the cell, making proteins, and producing energy are functions typically associated with other cell organelles like the cytoskeleton, ribosomes, and mitochondria, respectively.
