1. What is the term for the word part placed before a word to change its meaning?

• A. Prefix
• B. Affix
• C. Suffix
• D. Vocab

Correct answer: A

Rationale: The correct answer is 'Prefix.' A prefix is a word part that is placed before a root word to modify its meaning. In this case, a prefix changes the meaning of the root word. Choice B, 'Affix,' is a broader term that includes prefixes, suffixes, and infixes. Choice C, 'Suffix,' is a word part placed after a root word to modify its meaning, not before. Choice D, 'Vocab,' is unrelated to the word part placed before a word.

2. Solve for x: x/250 = 3/500

• A. 1.5
• B. 25.5
• C. 1500
• D. 2.5

Correct answer: A

Rationale: To solve for x in the equation x/250 = 3/500, you can cross-multiply: x*500 = 3*250. Therefore, 500x = 750. Now, divide both sides by 500: x = 750/500. Simplifying, x = 1.5. Therefore, the correct answer is A, 1.5. Choice B, 25.5, is incorrect as it does not match the correct calculation. Choice C, 1500, is incorrect as it is not the result of solving the equation given. Choice D, 2.5, is incorrect as well, as it does not align with the correct value of x obtained from the equation.

3. A blood vessel that is distended is ____

• A. Narrow
• B. Swollen
• C. Flat
• D. Dilated

Correct answer: B

Rationale: The correct answer is B: 'Swollen.' Distended means swollen or expanded, not narrow (A), flat (C), or dilated (D). When a blood vessel is distended, it is enlarged or swollen due to increased pressure.

4. What is the best description for an assembled product in the following sentence? The provisions apply to any “electronic product,” which is defined as any manufactured or assembled product (or component, part, or accessory of such product) that, when in operation, (i) contains or acts as part of an electronic circuit and (ii) emits electronic product radiation.

• A. A product that is collected
• B. A product that is legislated
• C. A product that is put together
• D. A product that is agreed upon

Correct answer: C

Rationale: The best description for an assembled product in the given sentence is "a product that is put together," as assembling refers to the action of putting together various parts or components to create a finished product. The sentence mentions that the provisions apply to any "assembled product" along with components, parts, or accessories of the product. Choice A, 'A product that is collected,' is incorrect as collecting does not imply assembling. Choice B, 'A product that is legislated,' is incorrect as legislation is related to laws and regulations, not the physical process of assembling. Choice D, 'A product that is agreed upon,' is incorrect as agreeing upon a product is unrelated to the physical act of assembling it.

5. In what type of covalent compounds are dispersion forces typically found?

• A. Polar
• B. Non-polar
• C. Ionic
• D. Hydrogen

Correct answer: B

Rationale: Dispersion forces, also known as London dispersion forces, are the weakest intermolecular forces that occur in non-polar covalent compounds. These forces result from temporary shifts in electron density within molecules, creating temporary dipoles. As a result, non-polar molecules, which lack a permanent dipole moment, can experience these dispersion forces. Polar compounds exhibit stronger intermolecular forces such as dipole-dipole interactions or hydrogen bonding, while ionic compounds involve electrostatic interactions between ions. Therefore, the correct answer is non-polar (choice B). Choices A, C, and D are incorrect because dispersion forces are typically found in non-polar covalent compounds, not polar, ionic, or hydrogen-bonded compounds.
