1. The realtor showed __________ and __________ a house on Wednesday afternoon. Which of the following pronoun pairs should be used in the blanks above?

• A. She, I
• B. She, me
• C. Me, her
• D. Her, me

Correct answer: D

Rationale: In the sentence, 'The realtor showed her and me a house on Wednesday afternoon,' the pronouns 'her' and 'me' are used as objects of the verb 'showed.' When choosing pronouns to fill in the blanks, it is important to use objective pronouns to maintain correct grammar and sentence structure. Choice A ('She, I') and Choice B ('She, me') are incorrect as 'I' and 'she' are subjective pronouns, not objective pronouns needed as objects in this sentence. Choice C ('Me, her') is also incorrect as the order and usage of pronouns are reversed from the correct form in the sentence.

2. Which fibrous connective tissue connects a muscle to a bone, allowing movement at a joint?

• A. Tendon
• B. Ligament
• C. Cartilage
• D. Bursa

Correct answer: A

Rationale: Tendons, the correct answer, are fibrous connective tissues that connect muscles to bones, enabling movement at joints. They play a crucial role in transmitting the force generated by muscles to the bones, facilitating movement. Ligaments (option B) connect bone to bone, providing stability to joints. Cartilage (option C) is a flexible tissue that acts as a cushion, reducing friction between bones in joints. Bursae (option D) are fluid-filled sacs located near joints that help reduce friction between tissues such as tendons and bones.

3. Isotopes are variants of a single element that differ in:

• A. Having the same number of protons but varying numbers of neutrons
• B. Having the same number of neutrons but varying numbers of protons
• C. Having the same mass but different atomic numbers
• D. None of the above

Correct answer: A

Rationale: Isotopes are variants of a single element that have the same number of protons, the defining characteristic of an element. They differ in the number of neutrons they possess, leading to isotopes having different atomic masses while retaining the same chemical properties. Choice B is incorrect because isotopes have the same number of neutrons and differ in the number of protons. Choice C is incorrect because isotopes have different masses due to varying numbers of neutrons, not different atomic numbers. Choice D is incorrect as isotopes do differ in the number of neutrons they possess.

4. Which adjective best describes the following setting: 'A lone cabin stood nestled amongst towering pines, smoke curling from its chimney into the crisp mountain air'?

• A. Bland
• B. Urban
• C. Idyllic
• D. Sterile

Correct answer: C

Rationale: The correct answer is 'Idyllic' because it accurately captures the peaceful and picturesque nature of the setting. The image of a lone cabin nestled among towering pines with smoke curling from its chimney into the crisp mountain air evokes a sense of tranquility and beauty. 'Bland' (choice A) is incorrect as it suggests something dull or uninteresting, which does not align with the vivid imagery described. 'Urban' (choice B) is also incorrect as it refers to a city or town setting, which is the opposite of the isolated cabin in the mountains. 'Sterile' (choice D) is incorrect as it conveys a lack of warmth and character, which is not reflective of the cozy and inviting atmosphere portrayed in the description.

5. When sugar is heated, it breaks down into carbon and water vapor. This is an example of a:

• A. Combination reaction
• B. Decomposition reaction
• C. Double displacement reaction
• D. Single displacement reaction

Correct answer: B

Rationale: The correct answer is B: Decomposition reaction. When sugar is heated, it undergoes a decomposition reaction where it breaks down into simpler substances, carbon, and water vapor. In a decomposition reaction, a single compound breaks down into two or more simpler substances. This process is the opposite of a combination reaction where two or more substances combine to form a new compound. Choice A, Combination reaction, is incorrect because a combination reaction involves the combination of two or more substances to form a new compound, which is the opposite of what happens when sugar breaks down. Choices C and D, Double displacement reaction and Single displacement reaction, are incorrect as they involve different mechanisms where the atoms or ions of the reactants are exchanged, which is not the case in the breakdown of sugar into carbon and water vapor.
