1. What is the fluid-filled, jelly-like substance within the cell that suspends the organelles called?

• A. Nucleus
• B. Cytoplasm
• C. Plasma membrane
• D. Golgi apparatus

Correct answer: B

Rationale: The correct answer is B, cytoplasm. Cytoplasm is the fluid-filled, jelly-like substance within the cell that suspends the organelles. The nucleus, not the correct answer, is the organelle that contains the cell's genetic material. The plasma membrane, another incorrect choice, is the outer boundary of the cell that regulates what enters and exits the cell. The Golgi apparatus, also an incorrect choice, is an organelle involved in processing and packaging proteins.

2. 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.

3. How much will Raoul expect to pay for his computer use at the library?

• A. $9
• B. $6
• C. $12
• D. $15

Correct answer: A

Rationale: Raoul estimates that he will need to use the library computer for approximately an hour and a half. Since each 15-minute period beyond the initial 30 minutes incurs a $3 charge, for a total of three additional 15-minute periods, Raoul will need to pay $9 ($3 x 3 = $9). Therefore, Raoul can expect to pay $9 for his computer use at the library. Choices B, C, and D are incorrect as they do not align with the information provided in the extract.

4. What are the three layers of the heart?

• A. Endocardium, myocardium, epicardium
• B. Pericardium, endocardium, myocardium
• C. Epicardium, myocardium, endocardium
• D. Pericardium, myocardium, endocardium

Correct answer: C

Rationale: The correct answer is C: Epicardium, myocardium, endocardium. The heart wall consists of three layers: the outer layer is the epicardium, the middle muscular layer is the myocardium, and the inner layer is the endocardium. Understanding the layers of the heart is essential for comprehending its structure and function. Choices A, B, and D are incorrect because they do not present the layers of the heart in the correct order. The pericardium is the outermost layer that surrounds the heart, but it is not part of the heart wall itself. Therefore, choices B and D are incorrect. Choice A is incorrect as it presents the layers in the wrong order, starting with the endocardium instead of the epicardium, which is the outermost layer.

5. How many centimeters are in 1 inch?

• A. 2.54 cm
• B. 3 cm
• C. 2 cm
• D. 1 cm

Correct answer: A

Rationale: The correct answer is A: 2.54 cm. One inch is equivalent to 2.54 centimeters. This conversion factor is commonly used when converting measurements between the metric and imperial systems. Choice B (3 cm) is incorrect as it is not the accurate conversion factor for 1 inch. Choice C (2 cm) is also incorrect as it does not reflect the correct conversion. Choice D (1 cm) is incorrect as it inaccurately states the conversion value for 1 inch.
