1. Which of the following makes a correction to an error in this sentence: The family sprinted through the airport, worryed they would miss their flight?

• A. 'family' should be 'families'
• B. 'worryed' should be 'worried'
• C. 'airport' should be 'airport'
• D. 'their' should be 'there'

Correct answer: B

Rationale: The error in the sentence lies in the misspelling of 'worryed,' which should be corrected to 'worried.' This choice addresses the grammatical mistake in the sentence. Choice A ('families') is incorrect as the sentence refers to a singular 'family.' Choice C ('airport' should be 'airport') is grammatically incorrect. Choice D ('their' should be 'there') is also incorrect; 'there' is used to indicate a place, while 'their' shows possession, neither of which is the error in the original sentence.

2. A dietitian wants to convince a patient to lose weight. Which statement below best communicates a scientific argument that justifies the need for weight loss?

• A. Losing weight can lower blood pressure, increase energy levels, and promote overall health.
• B. Society tends to treat overweight people unfairly.
• C. Members of the opposite sex are more interested in people who maintain a healthy weight.
• D. Losing weight is easy to do.

Correct answer: A

Rationale: Choice A is the correct answer as it provides a scientific argument supported by evidence. Losing weight has been shown to lower blood pressure, increase energy levels, and promote overall health. These are concrete health benefits that can be objectively measured and monitored. Choices B and C do not offer scientific justifications for weight loss but rather focus on societal perceptions and personal relationships. Choice D is incorrect as losing weight is not always easy and may require significant effort and lifestyle changes.

3. Which statement confirms that the cell membrane is selectively permeable?

• A. Receptors are found on a cell's surface.
• B. Cells communicate with each other using cell signals.
• C. Environmental changes can cause a cell to expand or shrink.
• D. Sodium ions must travel through ion channels to enter the cell.

Correct answer: D

Rationale: The correct answer is D because selective permeability is demonstrated by the fact that specific ions, such as sodium, require ion channels to cross the cell membrane. This process allows the cell to control what substances can enter or exit, highlighting the selective nature of the cell membrane. Choices A, B, and C do not directly relate to the concept of selective permeability of the cell membrane. Receptors on a cell's surface (Choice A) are involved in cell signaling rather than selective permeability. Cell communication through signals (Choice B) and environmental changes affecting cell size (Choice C) are not directly related to the selective permeability of the cell membrane, which specifically refers to the regulation of substances passing through the membrane.

4. What is the initial step a writer takes when generating new ideas for a writing task?

• A. Brainstorm
• B. Final edit
• C. Draft
• D. Revision

Correct answer: A

Rationale: When a writer begins a new writing task, the first step is typically brainstorming. Brainstorming involves generating new ideas, concepts, and approaches before moving on to drafting. Option B, 'Final edit,' is incorrect as it refers to the last stage of the writing process, where the writer reviews and makes final adjustments to the completed draft. Option C, 'Draft,' is incorrect as it comes after brainstorming and involves putting the ideas into a structured form. Option D, 'Revision,' is also incorrect as it involves making changes and improvements to the draft after the initial writing phase.

5. Which of the following is an example of a decomposition reaction?

• A. 2H2 + O2 → 2H2O
• B. CaCO3 → CaO + CO2
• C. 2Na + Cl2 → 2NaCl
• D. N2 + 3H2 → 2NH3

Correct answer: B

Rationale: A decomposition reaction involves a single compound breaking down into two or more simpler substances. In option B, CaCO3 breaks down into CaO and CO2, making it an example of a decomposition reaction. Options A, C, and D involve different types of chemical reactions such as synthesis, combination, and combustion, respectively. Option A represents a synthesis reaction, where two elements combine to form a compound. Option C demonstrates a combination reaction, where two elements combine to form a compound. Option D is an example of a synthesis reaction, where two reactants combine to form a single compound. It is important to recognize the specific characteristics of each type of chemical reaction to identify the correct example of decomposition reaction, where a compound breaks down into simpler products.
