1. The ankle bone may be called the ___________.

• A. talus
• B. talon
• C. fascia
• D. fascine

Correct answer: A

Rationale: The ankle bone is commonly known as the talus, which is a prominent bone in the human foot that forms the lower part of the ankle joint. It plays a crucial role in supporting body weight and allowing the foot to move in various directions. The terms talon and fascine are not accurate when referring to the ankle bone. Talon usually refers to the claw of a bird or animal, while fascine is a bundle of sticks used in construction or military engineering. Fascia, on the other hand, is a band of connective tissue and not a bone.

2. What is the main idea of the passage on Daylight Savings Time?

• A. Daylight Savings Time helps save energy.
• B. Daylight Savings Time is unnecessary and outdated.
• C. Daylight Savings Time is a law to conserve energy during wars.
• D. Daylight Savings Time was first implemented in Germany.

Correct answer: A

Rationale: The correct answer is A: "Daylight Savings Time helps save energy." The passage explains how Daylight Savings Time is implemented to take advantage of more daylight, which results in energy savings. By adjusting clocks ahead in spring, people can make use of additional daylight in the evenings, leading to reduced energy consumption. This measure was introduced to address energy crises and has been shown to save significant amounts of energy. Choice B is incorrect as the passage does not portray Daylight Savings Time as unnecessary or outdated; instead, it highlights its benefits. Choice C is partially correct but not the main idea of the passage, as saving energy is the primary focus. Choice D is mentioned in the passage but is not the main idea; the main idea is about the purpose and benefits of Daylight Savings Time.

3. How is the plasma membrane arranged?

• A. In a single layer made of proteins
• B. In a double layer made of proteins
• C. In a single layer of phospholipids
• D. In a double layer of phospholipids

Correct answer: D

Rationale: The plasma membrane is arranged in a double layer of phospholipids, known as a phospholipid bilayer. This structure consists of two layers of phospholipid molecules with hydrophilic heads facing the exterior and hydrophobic tails facing the interior, providing a semipermeable barrier for the cell. Choice A is incorrect because the plasma membrane is not made of a single layer of proteins. Choice B is incorrect as the double layer is composed of phospholipids, not proteins. Choice C is incorrect as the plasma membrane is not made of a single layer of phospholipids but rather a double layer.

4. Which word is not spelled correctly in the context of the following sentence? The attending physician led a small entourage of students and interns.

• A. attending
• B. lead
• C. entourage
• D. interns

Correct answer: B

Rationale: The correct answer is B, 'lead.' The correct spelling should be 'led' in the context of the sentence. 'Lead' is a present tense verb, while 'led' is the past tense of 'lead' when used in the sense of guiding or showing the way. Choice A, 'attending,' is spelled correctly. Choice C, 'entourage,' is spelled correctly. Choice D, 'interns,' is spelled correctly. The error lies in the verb 'lead' being used incorrectly in the past tense form.

5. In open-channel flow, a critical property is the free surface, which refers to the:

• A. Interface between the liquid and the container walls
• B. Interface between the liquid and a surrounding gas
• C. Bottom of the channel
• D. Region of highest velocity within the liquid

Correct answer: B

Rationale: The free surface in open-channel flow refers to the interface between the liquid and the surrounding gas, typically the atmosphere. This interface is critical as it determines the boundary between the liquid flow and the open environment. Option A is incorrect as it refers to the liquid-container wall interface, not the free surface. Option C is incorrect because it represents the bottom of the channel, not the free surface. Option D is incorrect as it describes the region of highest velocity within the liquid, not the free surface. Therefore, the correct choice is B.
