1. Long bones are one of the five major types of bones in the human body. All of the following bones are long bones, EXCEPT

• A. Thighs
• B. Forearms
• C. Ankles
• D. Fingers

Correct answer: D

Rationale: Long bones are one of the five major types of bones in the human body, characterized by their elongated shape. Thighs, forearms, and ankles are examples of long bones as they are longer than they are wide and have a tubular structure, aiding in support and movement. Fingers, however, are categorized as short bones due to their small size and shape. Short bones like fingers are essential for providing dexterity and precise movements rather than supporting weight or acting as levers for movement. Therefore, the correct answer is D, Fingers, as they are not classified as long bones.

2. What type of reaction is represented by the following equation: Fe2O3 (s) + 3H2 (g) -> 2Fe (s) + 3H2O (g)?

• A. Combustion
• B. Decomposition
• C. Single displacement
• D. Redox reaction

Correct answer: C

Rationale: The correct answer is C: Single displacement. This reaction is a single displacement reaction because the iron (Fe) in Fe2O3 is displaced by the hydrogen (H) in H2 to form Fe and H2O. In single displacement reactions, one element replaces another in a compound. Choice A, Combustion, involves a reaction with oxygen typically producing heat, light, and often a flame. Choice B, Decomposition, is when a compound breaks down into simpler substances. Choice D, Redox reaction, involves both reduction and oxidation reactions happening simultaneously, which is not the case in the provided equation.

3. What number is equivalent to -3 + 2 * 8 + 3?

• A. 11
• B. 31
• C. 28
• D. 80

Correct answer: B

Rationale: To solve this expression, we first follow the order of operations (PEMDAS/BODMAS). According to this rule, we start by multiplying 2 by 8, which equals 16. Then, we add -3 and 3 to get 0. Finally, adding 0 to 16 gives us the correct answer of 16. The correct answer is B. Choice A (11) results from adding all the numbers without considering the multiplication first. Choice C (28) is the result of adding all the numbers without considering any operations. Choice D (80) is incorrect as it does not correctly follow the order of operations.

4. In which of the following word pairs does the noun become a verb when the suffix is added?

• A. Biology, Biologist
• B. Apology, Apologize
• C. Happy, Happily
• D. Mineral, Mineralogy

Correct answer: B

Rationale: The correct answer is B. 'Apology' transforms into 'apologize' when the suffix is added, changing the word from a noun to a verb. In this case, the suffix '-ize' is added to the noun 'apology' to form the verb 'apologize.' Choices A, C, and D do not involve a transformation from a noun to a verb when a suffix is added. 'Biology' and 'biologist' are related but not in a noun-to-verb transformation. 'Happy' and 'happily' involve an adjective-to-adverb transformation. 'Mineral' and 'mineralogy' are related terms in the same field but do not show a noun-to-verb change.

5. Simplify the following expression: 1.034 + 0.275 - 1.294

• A. 0.015
• B. 0.15
• C. 1.5
• D. -0.15

Correct answer: A

Rationale: To simplify the expression, begin by adding 1.034 and 0.275, which equals 1.309. Then, subtract 1.294 from the sum: 1.309 - 1.294 = 0.015. Therefore, the correct answer is 0.015. Choice B (0.15) is incorrect as it does not reflect the accurate calculation. Choice C (1.5) is incorrect as it is not the correct result of the expression simplification. Choice D (-0.15) is incorrect as it represents a different value than the correct outcome of the expression simplification.
