1. Where are B-lymphocytes produced?

• A. Thymus
• B. Red bone marrow
• C. Lymph nodes
• D. Spleen

Correct answer: B

Rationale: B-lymphocytes are produced in the red bone marrow. The red bone marrow is the primary site for B-cell development, where they mature before entering the circulation. The thymus is responsible for T-lymphocyte maturation, not B-lymphocytes. Lymph nodes and spleen play roles in immune responses but are not the primary sites for B-lymphocyte production.

2. 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.

3. In the number 743.25, which digit represents the tenths place?

• A. 3
• B. 4
• C. 2
• D. 5

Correct answer: C

Rationale: In the number 743.25, the tenths place is the first digit to the right of the decimal point, which is 2. Therefore, the correct answer is C. Choice A (3) represents the hundredths place, choice B (4) represents the units place, and choice D (5) represents the hundredths place.

4. What does instigate mean?

• A. Deactivate
• B. Activate
• C. Suppress
• D. Evaluate

Correct answer: B

Rationale: The correct answer is B: 'Activate.' Instigate means to initiate or provoke a particular event or action. Choice A, 'Deactivate,' is incorrect as it means to make something inactive, which is the opposite of instigate. Choice C, 'Suppress,' is incorrect as it means to restrain or prevent something, not to initiate it. Choice D, 'Evaluate,' is incorrect as it means to assess or judge the value or quality of something, not to start or provoke it.

5. Two students _________ their professor about the possibility of obtaining a good grade in class.

• A. Ask
• B. Is
• C. Was
• D. Could

Correct answer: A

Rationale: The correct answer is 'Ask' because it maintains subject-verb agreement with 'two students,' requiring a plural verb 'ask' to match the plural subject. The other choices ('Is,' 'Was,' 'Could') do not agree with the plural subject and are thus incorrect. 'Is' is singular, 'Was' is the past tense form, and 'Could' indicates a possibility but does not fit the context of the sentence.
