1. A worker ships 25 boxes each day. Each box contains 3 shipping labels. The inventory has 500 shipping labels. How many days will it take to use the inventory of shipping labels? Round to the nearest whole.

• A. 7 days
• B. 8 days
• C. 20 days
• D. 6 days

Correct answer: A

Rationale: To find out how many days it will take to use the 500 shipping labels, multiply the number of labels used per day (25 boxes * 3 labels/box = 75 labels) by the total number of days the inventory will last (500 labels ÷ 75 labels/day = 6.67 days). Rounded to the nearest whole number, it will take 7 days to use the inventory of shipping labels. Choice B (8 days) is incorrect because the calculation yields 6.67 days, which rounds down to 6 days, making it an incorrect answer. Choice C (20 days) and Choice D (6 days) are also incorrect as they are not the nearest whole number to the correct answer of 7 days.

2. When are gallstones most problematic?

• A. When they block a duct
• B. When they contain cholesterol
• C. When they contain bilirubin
• D. When they begin to dissolve

Correct answer: A

Rationale: Gallstones become most problematic when they block a duct, such as the bile duct or cystic duct. This blockage can lead to various complications, including inflammation, infection, and even damage to the gallbladder or liver. In severe cases, a blocked duct can cause intense pain, jaundice, and other serious symptoms that require medical intervention. Choices B, C, and D are incorrect because the presence of cholesterol or bilirubin in gallstones or the process of dissolution do not necessarily indicate when gallstones become most problematic. The critical issue arises when the stones obstruct a duct, leading to complications.

3. What is stated in the passage about Sleep Apnea?

• A. Sleep apnea causes chronic illness.
• B. Sleep apnea affects intellectual abilities.
• C. Sleep apnea leads to early death.
• D. Sleep apnea causes breathing interruptions.

Correct answer: D

Rationale: The correct answer is 'D: Sleep apnea causes breathing interruptions.' The passage explicitly mentions sleep apnea as a condition where an individual stops breathing during sleep, indicating breathing interruptions. Choice A is incorrect because the passage does not directly state that sleep apnea causes chronic illness. Choice B is incorrect because the passage discusses how lack of sleep affects intellectual abilities but does not specifically attribute this to sleep apnea. Choice C is incorrect as the passage does not mention sleep apnea leading to early death. Therefore, the most accurate statement about sleep apnea based on the passage is that it causes breathing interruptions.

4. What is another word for acrid?

• A. Bitter
• B. Smoky
• C. Nimble
• D. Severe

Correct answer: A

Rationale: Acrid is often used to describe a sharp, unpleasant smell or taste, which is synonymous with bitterness. The word 'bitter' closely relates to the strong and sharp sensation associated with acrid qualities. Choice B, 'Smoky,' does not capture the sharpness or unpleasantness associated with acrid, as it refers more to the presence of smoke. Choice C, 'Nimble,' and choice D, 'Severe,' are unrelated to the meaning of acrid and do not serve as synonyms in this context.

5. Which of the following arrangement is seen in the plasma membrane?

• A. Lipids with embedded proteins
• B. An outer lipid layer and an inner lipid layer
• C. Proteins embedded in lipid bilayer
• D. Altering protein and lipid layers

Correct answer: C

Rationale: The correct arrangement seen in the plasma membrane is proteins embedded in the lipid bilayer. The plasma membrane is composed of a lipid bilayer with embedded proteins. These proteins perform various functions such as transport, signaling, and structural support within the cell membrane. This arrangement allows for the selective permeability of the membrane and facilitates communication between the cell and its environment. Choices A, B, and D are incorrect because the primary arrangement in the plasma membrane involves proteins being embedded in the lipid bilayer, not lipids with embedded proteins, an outer and inner lipid layer, or altering protein and lipid layers.
