1. How many inches are in 2 yards?

• A. 36 inches
• B. 48 inches
• C. 60 inches
• D. 72 inches

Correct answer: D

Rationale: To convert yards to inches, remember that there are 36 inches in a yard. Therefore, when you have 2 yards, multiplying 36 inches by 2 results in 72 inches. Choice A, 36 inches, is the number of inches in 1 yard, not 2 yards. Choice B, 48 inches, and Choice C, 60 inches, are incorrect calculations based on the conversion factor of 36 inches per yard.

2. What does alimentary mean?

• A. Related to nourishment
• B. Related to outflow
• C. Related to simplicity
• D. Related to protection

Correct answer: A

Rationale: The term 'alimentary' is used to describe things that are related to nourishment or the process of providing food or nourishment. It is often associated with the digestive system and the intake of food. Therefore, the correct answer is A: Related to nourishment. Choice B, 'Related to outflow,' is incorrect because alimentary is not associated with outflow but rather with intake. Choice C, 'Related to simplicity,' and choice D, 'Related to protection,' are unrelated to the meaning of alimentary.

3. When calculating an object’s acceleration, what must you do?

• A. Divide the change in time by the velocity.
• B. Multiply the velocity by the time.
• C. Find the difference between the time and velocity.
• D. Divide the change in velocity by the change in time.

Correct answer: D

Rationale: When calculating an object's acceleration, you must divide the change in velocity by the change in time. Acceleration is defined as the rate of change of velocity with respect to time. By determining the ratio of the change in velocity to the change in time, you can ascertain how quickly the velocity of an object is changing, thereby finding its acceleration. Choice A is incorrect because acceleration is not calculated by dividing time by velocity. Choice B is incorrect as it describes multiplying velocity by time, which does not yield acceleration. Choice C is incorrect as finding the difference between time and velocity is not a method to calculate acceleration.

4. What does oral mean?

• A. Through the skin
• B. Given through or affecting the mouth
• C. Injected
• D. Absorbed through digestion

Correct answer: B

Rationale: The correct answer is B: 'Given through or affecting the mouth.' Oral medications are those that are taken by mouth. Choice A is incorrect as 'Through the skin' refers to something being absorbed through the skin, not through the mouth. Choice C, 'Injected,' is incorrect as oral administration does not involve injection but rather ingestion. Choice D, 'Absorbed through digestion,' is partially correct in that oral medications are indeed absorbed through the digestive system, but the term 'oral' specifically refers to the mouth in this context.

5. Which best defines the molarity of an aqueous sugar solution?

• A. Grams of sugar per milliliter of solution
• B. Moles of sugar per milliliter of solution
• C. Grams of sugar per liter of solution
• D. Moles of sugar per liter of solution

Correct answer: D

Rationale: The molarity of a solution is defined as the number of moles of solute per liter of solvent. In the case of an aqueous sugar solution, the molarity would be expressed as moles of sugar per liter of solution. This is because molarity is a measurement of the concentration of a solute in a solution based on the number of moles present in a given volume of the solution. Therefore, the correct answer is D. Choices A, B, and C are incorrect because the molarity is specifically defined in terms of moles of solute per liter of solution, not in grams per milliliter or grams per liter. Molarity is a unit of concentration that relates the amount of solute to the volume of the solution, not the mass of the solute.
