1. What is 0.07 as a simplified fraction?

• A. 7/100
• B. 7/50
• C. 7/25
• D. 7/10

Correct answer: A

Rationale: The decimal 0.07 can be expressed as the fraction 7/100, where 7 is the numerator and 100 is the denominator. To simplify the fraction, you divide both the numerator and denominator by their greatest common divisor, which in this case is 1. Therefore, 7/100 is already in its simplest form and cannot be further simplified. Choices B, C, and D are incorrect fractions as they do not represent the decimal 0.07.

2. Which of the following is an example of a secondary source that would be used in a documentary about World War I?

• A. an essay by a historian about the lasting effects of the war
• B. photographs of military equipment used in the war
• C. a recorded interview with a veteran who fought for the US Army
• D. letters written by soldiers to their families

Correct answer: A

Rationale: An essay by a historian about the lasting effects of the war is an example of a secondary source as it provides analysis and interpretation of primary sources like official documents, photographs, and letters. It offers a perspective that is based on research and not directly involved in the events, making it a valuable resource for understanding the historical context of World War I. Choice B, photographs of military equipment, is a primary source as it provides direct visual evidence from the time period. Choice C, a recorded interview with a veteran, is also a primary source as it offers firsthand accounts from someone directly involved in the events. Choice D, letters written by soldiers, are primary sources that offer insights into the personal experiences of individuals during the war.

3. Which of the following accurately describes saltatory conduction?

• A. It is faster than normal nerve conduction
• B. It occurs from one node of Ranvier to the next
• C. It only occurs in myelinated neurons
• D. All of the above

Correct answer: D

Rationale: The correct answer is D, 'All of the above.' Saltatory conduction is faster than normal nerve conduction, occurs from one node of Ranvier to the next, and is exclusive to myelinated neurons. This form of conduction allows for the rapid transmission of nerve impulses by the action potential jumping between the nodes of Ranvier in myelinated neurons, enhancing the efficiency of signal propagation along the axon. Choice A is correct as saltatory conduction is indeed faster than normal conduction. Choice B is accurate as it describes the mechanism of conduction 'jumping' from one node of Ranvier to the next. Choice C is correct because saltatory conduction occurs specifically in myelinated neurons where the myelin sheath insulates the axon except at the nodes of Ranvier, facilitating faster transmission of nerve impulses.

4. What is the process called in which a substance changes from a gas to a liquid?

• A. Condensation.
• B. Evaporation.
• C. Sublimation.
• D. Vaporization.

Correct answer: A

Rationale: Condensation is indeed the correct answer. It is the process by which a substance changes from a gas to a liquid. This occurs when the temperature of a gas decreases enough for its particles to lose energy and come together to form a liquid. On the other hand, evaporation is the process of a liquid changing to a gas. Sublimation is the direct transition of a substance from a solid to a gas without passing through the liquid phase. Vaporization, on the other hand, is the general term for the process of a liquid changing to a gas, which includes both evaporation and boiling.

5. Select the correct verb to complete the following sentence: I _________ about it for a long time before I decided to major in criminal justice.

• A. think
• B. thank
• C. thinked
• D. thought

Correct answer: D

Rationale: The correct answer is 'thought.' 'Thought' is the correct past tense form of 'think.' In this sentence, 'thought' is used to indicate that the thinking process happened in the past before deciding to major in criminal justice. Choices A, B, and C are incorrect. 'Think' is the present tense form, 'thank' is a different verb with a different meaning, and 'thinked' is not a valid past tense form of 'think.'
