1. Select the word that means 'about to happen.'
- A. depending
- B. offending
- C. suspending
- D. impending
Correct answer: D
Rationale: The correct answer is 'impending,' which means something that is about to happen. Choices A, B, and C do not have the same meaning. 'Depending' refers to relying on something, 'offending' means causing anger or resentment, and 'suspending' means temporarily stopping or delaying something.
2. What is the result of the expression 4/5 + 6/7?
- A. 1 23/35
- B. 2 5/7
- C. 1 1/7
- D. 1 3/4
Correct answer: A
Rationale: To add fractions with different denominators, you first need to find a common denominator. In this case, the common denominator for 5 and 7 is 35. Then, convert each fraction to have a denominator of 35. 4/5 becomes 28/35, and 6/7 becomes 30/35. Adding these fractions together gives 58/35, which simplifies to 1 23/35. Therefore, the correct answer is A, 1 23/35. Choice B, 2 5/7, is incorrect because it does not match the correct result. Choice C, 1 1/7, is incorrect as it is not the simplified form of the sum of the fractions. Choice D, 1 3/4, is incorrect as it is a different result and not the sum of 4/5 and 6/7.
3. Lights out on the base is at 10:30 P.M. What would that be in military time?
- A. 1030
- B. 1300
- C. 1230
- D. 2230
Correct answer: D
Rationale: In military time, the time of 10:30 P.M. is represented as 2230. Military time follows a 24-hour clock system where hours are not converted to a 12-hour clock. Each hour is represented from 00 to 23. Therefore, 10:30 P.M. in military time is 2230. Choice A, 1030, is incorrect as it represents 10:30 A.M. Choice B, 1300, stands for 1:00 P.M., and Choice C, 1230, is equivalent to 12:30 P.M. Hence, the correct answer is D.
4. Two organisms live in a relationship from which both benefit. What is this called?
- A. Mutualism
- B. Parasitism
- C. Commensalism
- D. Competition
Correct answer: A
Rationale: Mutualism is a type of symbiotic relationship between two organisms in which both parties benefit from the association. It is a mutually beneficial interaction where both organisms gain something valuable, such as food, protection, or some other resource. This contrasts with parasitism, where one organism benefits at the expense of the other, commensalism, where one organism benefits while the other is unaffected, and competition, where both organisms are negatively affected by their interaction.
5. The patient made a ritualistic arranging of the food on his plate. Which word best describes the patient's repetitive behavior?
- A. Formal
- B. Ritualistic
- C. Formalizing
- D. Ritual
Correct answer: B
Rationale: The correct answer is 'Ritualistic.' This adjective describes actions performed in a habitual or ceremonial manner, which aligns with the context of the patient's repeated arrangement of food. 'Formal' (choice A) does not capture the repetitive nature of the behavior. 'Formalizing' (choice C) refers to the process of making something formal rather than describing repetitive behavior. 'Ritual' (choice D) is a noun and does not best describe the patient's behavior in this context.
