1. Muscles that work together to produce a specific movement are called

• A. Antagonistic muscles
• B. Agonistic muscles
• C. Synergistic muscles
• D. Flexors and extensors

Correct answer: C

Rationale: Synergistic muscles are groups of muscles that work together in a coordinated manner to produce a specific movement. They synchronize their actions to achieve a common goal efficiently. In contrast, antagonistic muscles work in opposing directions, and agonistic muscles, also known as prime movers, are responsible for initiating a movement. Flexors and extensors represent muscles that perform contrasting actions around a joint, such as bending and straightening. Therefore, the correct answer is C - 'Synergistic muscles,' as they collaborate to facilitate a specific movement, unlike the other choices which describe different muscle functions within the body.

2. Archie says, 'Northerners eat bland food.' The most precise definition of this statement is

• A. A stereotype
• B. An inference
• C. A bias
• D. A generalization

Correct answer: A

Rationale: The correct answer is A: a stereotype. Archie's statement about Northerners eating bland food reflects a stereotype, which is an oversimplified and generalized belief about a particular group of people. This statement is not an inference because it is not based on evidence or reasoning. It is also not a bias, which is a preference or inclination that inhibits impartial judgment. While the statement could be seen as a generalization, it more specifically fits the definition of a stereotype due to its oversimplified and exaggerated nature.

3. What is the general formula for an alcohol?

• A. CₙH₂ₙ
• B. CₙH₂ₙ₊₂
• C. CₙH₂ₙ₋₁
• D. CₙH₂ₙO

Correct answer: D

Rationale: The correct general formula for an alcohol is CnH2n+1OH, which can be simplified to CnH2nO. In this formula, 'n' represents the number of carbon atoms, '2n' represents the number of hydrogen atoms, and 'O' represents the oxygen atom present in the hydroxyl group of the alcohol. Therefore, the correct general formula for an alcohol is CnH2nO. Choice A, CₙH₂ₙ, does not account for the oxygen atom, which is essential in alcohols. Choice B, CₙH₂ₙ₊₂, does not include the oxygen atom or the necessary hydrogen atoms for the hydroxyl group. Choice C, CₙH₂ₙ₋₁, lacks the oxygen atom and also does not fulfill the requirements of the hydroxyl group. Thus, the most accurate representation of the general formula for an alcohol is CnH2nO.

4. What is 0.25 mg to mcg?

• A. 250 mcg
• B. 25 mcg
• C. 2.5 mcg
• D. 2500 mcg

Correct answer: A

Rationale: To convert milligrams (mg) to micrograms (mcg), you multiply by 1000 because 1 mg is equal to 1000 mcg. Therefore, 0.25 mg is equal to 250 mcg. Choices B, C, and D are incorrect as they do not consider the correct conversion factor.

5. Which of the following choices represents the best label for this passage?

• A. definition essay
• B. cause/effect essay
• C. comparison essay
• D. persuasive essay

Correct answer: A

Rationale: The passage provides factual information and details about the loss of barrier islands due to erosion and its impact on coastal communities. It focuses on defining and describing the issue rather than analyzing causes and effects, making it best classified as a definition essay. Choice B, cause/effect essay, would require a deeper exploration into the causes and effects of the erosion. Choice C, comparison essay, would involve comparing different aspects or scenarios, which is not the focus here. Choice D, persuasive essay, aims to convince the reader of a particular viewpoint, which is not the purpose of this passage.
