1. 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.

2. Based on the word choices in the following sentence, which of the following is the most likely meaning of the prefix per-?

• A. Across
• B. By
• C. With
• D. Through

Correct answer: D

Rationale: The prefix 'per-' commonly means 'through,' indicating movement from one side to the other or completely through something. In this context, 'through' is the most fitting interpretation as it aligns with the idea of complete passage or thorough involvement. The other options do not convey the concept of going completely through something. 'Across' implies moving from one side to another but not necessarily all the way through. 'By' denotes proximity or secondary involvement rather than passage through. 'With' indicates accompaniment or association, which is not reflective of the prefix per- in terms of movement or completion.

3. Which of the following is listed in order from least to greatest?

• A. -2 3/4, -2 7/8, -1/5, 2/5, 1/8
• B. -1/5, 1/8, 2/5, -2 3/4, -2 7/8
• C. -2 7/8, -2 3/4, -1/5, 1/8, 2/5
• D. 1/8, 2/5, -1/5, -2 7/8, -2 3/4

Correct answer: C

Rationale: To determine the order from least to greatest, we can convert all fractions and mixed numbers to decimals or use a least common denominator. Converting the fractions in Choice C to decimals, we get -2.875, -2.75, -0.2, 0.125, and 0.4 when reading from left to right. Negative integers with larger absolute values are less than negative integers with smaller absolute values. Therefore, the correct answer is Choice C. Choices A, B, and D are incorrect because they do not present the numbers in the correct order from least to greatest when converted to decimals or compared using common denominators.

4. What is the perimeter of a rectangle with a length of 7 cm and a width of 3 cm?

• A. 21 cm
• B. 10 cm
• C. 14 cm
• D. 20 cm

Correct answer: D

Rationale: To find the perimeter of a rectangle, you add the lengths of all its sides. In this case, the formula for the perimeter of a rectangle is 2*(length + width). Substituting the given values, we get: 2*(7 cm + 3 cm) = 2*(10 cm) = 20 cm. Therefore, the correct answer is 20 cm. Choice A (21 cm) is incorrect because it is the sum of the individual sides rather than the perimeter. Choice B (10 cm) is incorrect because it only represents one side of the rectangle. Choice C (14 cm) is incorrect as it is not the total perimeter of the rectangle.

5. T cells in the immune system can be categorized into different types. What type of T cell directly kills infected body cells?

• A. Helper T cells
• B. Cytotoxic T cells
• C. Regulatory T cells
• D. Memory T cells

Correct answer: B

Rationale: Cytotoxic T cells directly kill infected body cells by recognizing specific antigens on the surface of infected cells and releasing cytotoxic substances to induce cell death, eliminating the infected cells. Helper T cells assist in coordinating the immune response, regulatory T cells help maintain immune tolerance, and memory T cells mount a faster and stronger response upon re-exposure to a previously encountered antigen. Therefore, the correct answer is cytotoxic T cells as they play a crucial role in directly targeting and destroying infected cells.
