1. Choose the correct form of the verb: 'She ______ the best student in her class.'

• A. is
• B. are
• C. were
• D. am

Correct answer: A

Rationale: The subject 'She' is singular, so the correct verb form is 'is.' In this sentence, the verb needs to agree with the singular subject 'She.' 'Are' (B), 'were' (C), and 'am' (D) are all incorrect as they are plural or the wrong form for the subject 'She.'

2. What is the least common denominator for the fractions below? 1/2, 2/3, 4/5

• A. 30
• B. 25
• C. 7
• D. 19

Correct answer: A

Rationale: To find the least common denominator for fractions 1/2, 2/3, and 4/5, we need to identify the least common multiple of the denominators. The denominators are 2, 3, and 5. The least common multiple of 2, 3, and 5 is 30. Therefore, 30 is the least common denominator for these fractions. Choice B (25), C (7), and D (19) are incorrect because they are not the least common multiple of the denominators of the given fractions.

3. Which of the following could accurately subtitle this passage?

• A. The start of the revolution
• B. American march from the sea
• C. The full armies face off
• D. In the state of Massachusetts

Correct answer: A

Rationale: The passage outlines significant events in Clara Barton's life, starting from her birth in Massachusetts, moving to Washington D.C., her humanitarian work during the Civil War, and her later efforts in Europe and with the Red Cross. The most accurate subtitle for this passage would be 'The start of the revolution,' as it refers to the beginning and progression of Barton's revolutionary work in humanitarian aid and establishing the American branch of the International Red Cross Organization. The other choices are not suitable subtitles as they do not encompass the breadth of Barton's impactful life events described in the passage.

4. What is the pathway of oxygenated blood from the lungs?

• A. Lungs to the left atrium, through the mitral valve into the left ventricle, pumped into the aorta upon contraction, then dispersed to tissues via a network of arteries and capillaries
• B. Lungs to the right atrium, through the mitral valve into the right ventricle, pumped into the aorta upon contraction, then dispersed to tissues via a network of arteries and veins
• C. Lungs to the left atrium, directly to the right aorta, then dispersed to tissues via a network of arteries and capillaries
• D. Lungs to the left atrium, through the septal valve, stored in the left ventricles, then dispersed to tissues via a network of arteries and capillaries

Correct answer: A

Rationale: The correct pathway of oxygenated blood from the lungs is as follows: Oxygenated blood travels from the lungs to the left atrium, then passes through the mitral valve into the left ventricle. From there, it is pumped into the aorta upon contraction of the heart and is then dispersed to various tissues throughout the body via a network of arteries and capillaries. Choice B is incorrect as it incorrectly mentions the right atrium and ventricle, which are associated with deoxygenated blood. Choice C is incorrect as it mentions a direct connection to the right aorta, which does not exist in the circulatory system. Choice D is incorrect as it refers to the septal valve (which is not anatomically correct) and storing blood in the left ventricle, which does not occur in the normal circulation of blood.

5. What is the correct plural of chair?

• A. Chair
• B. Chairs
• C. Chaires
• D. Chairies

Correct answer: B

Rationale: The correct plural form of 'chair' is 'chairs,' following the regular pluralization rule by adding 's.' Choices C and D, 'Chaires' and 'Chairies,' are incorrect because they do not follow the standard English pluralization rule. Choice A, 'Chair,' is the singular form and not the plural form of the word.
