1. Solve: 2 - 8(24 ÷ 2).

• A. -94
• B. -92
• C. -96
• D. -90

Correct answer: A

Rationale: To solve the expression, we follow the order of operations (PEMDAS). First, we divide 24 by 2 to get 12. Then, we multiply 8 by 12, which equals 96. Finally, we subtract 96 from 2: 2 - 96 = -94. Therefore, the correct answer is A, '-94'. Choices B, C, and D are incorrect as they do not follow the correct order of operations or make errors during calculation.

2. Which word is NOT used correctly in the sentence? "You should always do the write thing."

• A. Do
• B. Always
• C. Write
• D. Should

Correct answer: C

Rationale: "Write" is incorrect in this context. It should be "right," referring to the correct or moral action.

3. Which plane would you use to separate the abdominal cavity from the thoracic cavity?

• A. Sagittal
• B. Transverse
• C. Frontal
• D. Coronal

Correct answer: B

Rationale: The transverse plane, also known as the horizontal plane, runs horizontally from left to right, dividing the body into superior (upper) and inferior (lower) parts. This plane is ideal for separating the abdominal cavity (located below) from the thoracic cavity (located above). The sagittal plane (choice A) divides the body into left and right portions, the frontal plane (choice C) divides the body into front and back portions, and the coronal plane (choice D) is another term for the frontal plane. Therefore, when looking to separate the abdominal cavity from the thoracic cavity, the transverse plane is the most appropriate choice.

4. Which type of passive transport uses proteins that change shape to move a target molecule through the membrane?

• A. Diffusion
• B. Carrier proteins
• C. Channel proteins
• D. None of the above

Correct answer: B

Rationale: The correct answer is B: Carrier proteins. Carrier proteins are involved in facilitated diffusion, a type of passive transport where specific target molecules are moved across the membrane with the help of proteins that change shape. These carrier proteins bind to the target molecule on one side of the membrane, undergo a conformational change, and then release the molecule on the other side. This process is crucial for the selective transport of certain molecules that cannot pass through the membrane by simple diffusion. Choices A and C are incorrect because diffusion and channel proteins do not involve proteins that change shape to transport target molecules selectively. Choice D is incorrect as carrier proteins fit the description provided in the question.

5. Identify the overall tone of the essay about Aromatherapy.

• A. Congratulatory.
• B. Uncertain.
• C. Annoyed.
• D. Distressed.

Correct answer: B

Rationale: The tone of the essay is uncertain, as the author questions the validity of aromatherapy based on the study's results. The phrasing "does not necessarily prove that aromatherapy is worthless" indicates a hesitance to fully endorse or dismiss its value. This ambiguity throughout the passage reinforces the uncertain tone, aligning it with choice B.
