1. What is 60% of 90?

• A. 54
• B. 58
• C. 60
• D. 65

Correct answer: A

Rationale: To find 60% of 90, you multiply 90 by 0.60 (which is the decimal form of 60%). So, 90 * 0.60 = 54. Therefore, 60% of 90 is 54. Choice A is correct. Choice B, C, and D are incorrect as they do not reflect the correct calculation for finding 60% of 90.

2. As used in the last sentence of this paragraph, the term 'concomitant' means?

• A. Accompanying
• B. Quiet
• C. Frustrated
• D. Prefer low-pitched tones

Correct answer: A

Rationale: In the provided extract, the term 'concomitant' is used to describe problems associated with alcohol abuse, such as the individual becoming alcoholic, contribution to highway deaths by drunken drivers, and spousal and child abuse. Therefore, in this context, 'concomitant' means accompanying, or going along with something else. The other choices of 'Quiet,' 'Frustrated,' and 'Prefer low-pitched tones' do not align with the meaning of 'concomitant' as used in the paragraph.

3. What is the correct formula for sodium nitrate?

• A. NaNO
• B. Na NO
• C. NaNO₃
• D. Na NO₂

Correct answer: C

Rationale: The correct formula for sodium nitrate is NaNO₃. In this formula, 'Na' represents sodium, 'N' represents nitrogen, and 'O₃' represents three oxygen atoms. Sodium nitrate consists of one sodium ion (Na⁺) and one nitrate ion (NO₃⁻), which means the correct formula is NaNO₃. Choice A (NaNO) is incorrect as it lacks the subscript indicating the presence of three oxygen atoms. Choice B (Na NO) is incorrect as it includes a space between 'Na' and 'NO', which is not part of the standard chemical formula notation. Choice D (Na NO₂) is incorrect as it indicates a different compound with a nitrite ion (NO₂⁻) instead of nitrate ion.

4. What is the name of the structure that prevents food from entering the airway?

• A. trachea
• B. esophagus
• C. diaphragm
• D. epiglottis

Correct answer: D

Rationale: The epiglottis is the structure that prevents food from entering the airway. It acts as a lid over the trachea during swallowing, directing food to the esophagus instead of the windpipe (trachea). The trachea (Choice A) is the windpipe that allows air to pass into the lungs, the esophagus (Choice B) is the tube that carries food from the mouth to the stomach, and the diaphragm (Choice C) is a muscle involved in breathing and not in preventing food passage.

5. In the address 'Mr. Ryan, 1600 Pennsylvania Ave., Washington, DC 20003,' which word is the salutation?

• A. 1600 Pennsylvania Ave.
• B. 20003 (Area code)
• C. Ryan
• D. Mr.

Correct answer: D

Rationale: The correct answer is 'D - Mr.' The salutation is the formal title used before a person's name, which in this case is 'Mr.' Other choices are incorrect as '1600 Pennsylvania Ave.' is the street address, '20003' is the zip code, and 'Ryan' is the recipient's name.
