1. Which property of a substance refers to its ability to be stretched into thin wires?

• A. Conductivity
• B. Viscosity
• C. Ductility
• D. Malleability

Correct answer: C

Rationale: Ductility is the property of a substance that allows it to be stretched into thin wires without breaking. It is a crucial property for materials used in wire production. Conductivity refers to the ability of a substance to conduct electricity or heat, not to be stretched into wires. Viscosity is the measure of a fluid's resistance to flow, not its ability to be stretched. Malleability is the property of a substance that allows it to be hammered or rolled into thin sheets, not stretched into wires.

2. What must you always use in all math?

• A. PEMDAS
• B. Variables
• C. Conversion factors
• D. Estimation

Correct answer: A

Rationale: The correct answer is A: PEMDAS. PEMDAS stands for the order of operations: Parentheses, Exponents, Multiplication and Division (left to right), Addition and Subtraction (left to right). It is a fundamental rule to follow in mathematics to ensure calculations are done correctly. Choices B, C, and D are incorrect as they do not encompass the essential rule that PEMDAS provides for solving mathematical expressions.

3. Based on the passages, what can we infer about the relationship between assault and lethal force?

• A. An act of lethal force always results from a type of assault.
• B. An assault will lead to the use of lethal force by someone.
• C. An assault with deadly intent can lead to an individual using lethal force to preserve their well-being.
• D. If someone uses self-defense in a conflict, it is considered deadly force; if actions or threats are intended, it is classified as assault.

Correct answer: C

Rationale: From the passages provided, it can be inferred that an assault with deadly intent can lead to an individual using lethal force to defend themselves and preserve their well-being. This suggests a relationship between assault with deadly intent and the potential use of lethal force in self-defense situations. Choice A is incorrect because lethal force is not always a direct result of assault, as it depends on the circumstances. Choice B is incorrect as not all assaults lead to the use of lethal force by someone. Choice D is incorrect as the definition of deadly force and assault are distinct, with deadly force typically being used in self-defense situations where there is an immediate threat of severe harm or death.

4. Which muscles play a significant role in the process of forced exhalation by contracting to reduce the thoracic cavity volume?

• A. Diaphragm
• B. External intercostal muscles
• C. Internal intercostal muscles
• D. Abdominal muscles

Correct answer: D

Rationale: The abdominal muscles play a significant role in forced exhalation by contracting to reduce the thoracic cavity volume. When these muscles contract, the pressure within the thoracic cavity increases, assisting in the expulsion of air from the lungs. This action helps to compress the abdomen and push the diaphragm upwards, further decreasing the volume of the thoracic cavity and aiding in the exhalation process. The diaphragm (Choice A) is mainly involved in inhalation by contracting and moving downward to increase thoracic cavity volume. External intercostal muscles (Choice B) and internal intercostal muscles (Choice C) are primarily involved in the process of inhalation by expanding the thoracic cavity during normal breathing, rather than forced exhalation.

5. Logan had already forgiven Marianne for telling his secret, and so when he was presented with a chance to treat her in kind, he simply did what he did best—he kept his mouth shut. Which of the words in the sentence above is a past participle?

• A. telling
• B. forgiven
• C. and
• D. treat

Correct answer: B

Rationale: The correct answer is 'forgiven' as it is a past participle. A past participle is used to indicate an action that has already occurred in the past. In this sentence, 'forgiven' describes the state of Logan having forgiven Marianne. Choice A, 'telling', is a present participle, not a past participle, which is used for ongoing or continuous actions. Choice C, 'and', is a conjunction that connects phrases or words. Choice D, 'treat', is a verb in its base form, not a past participle.
