1. Imagine you have an element with atomic number 20 and mass number 40. How many neutrons does it have?

• A. 20
• B. 40
• C. 10
• D. 20

Correct answer: C

Rationale: - The atomic number (Z) represents the number of protons in an atom. In this case, the atomic number is 20. - The mass number (A) represents the total number of protons and neutrons in an atom. In this case, the mass number is 40. - To find the number of neutrons, you subtract the atomic number from the mass number: Neutrons = Mass number - Atomic number. - Neutrons = 40 - 20 = 20. - Therefore, the element with atomic number 20 and mass number 40 has 20 neutrons.

2. What can the reader infer from this passage?

• A. The children tortured Gulliver.
• B. Gulliver traveled because he wanted to meet new people.
• C. Gulliver is considerably larger than the children who are playing around him.
• D. Gulliver has a genuine love and enthusiasm for people of all sizes.

Correct answer: C

Rationale: The correct answer is C. In the passage, it is mentioned that the children play in Gulliver's hair, implying that he is considerably larger than them. This suggests that Gulliver is of a significant size compared to the children. Choice A is incorrect as there is no indication of the children torturing Gulliver in the passage. Choice B is incorrect because the passage does not mention Gulliver's reason for traveling. Choice D is incorrect as the passage does not provide evidence of Gulliver's love and enthusiasm for people of all sizes.

3. 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.

4. What type of error occurs in the sentence 'Everyone knew who the culprit was, except for me'?

• A. Subject-verb agreement
• B. Misplaced modifier
• C. Dangling participle
• D. Pronoun-antecedent agreement

Correct answer: B

Rationale: The error in the sentence is a misplaced modifier. The phrase 'except for me' should ideally modify 'me,' but it is incorrectly placed after 'knew,' leading to confusion about who the exception applies to. 'Subject-verb agreement' is incorrect as there is no disagreement between the subject and the verb. 'Dangling participle' is incorrect as there are no dangling participles in the sentence. 'Pronoun-antecedent agreement' is incorrect as the pronoun 'me' correctly refers to the antecedent 'I'; the issue lies with the placement of the modifier.

5. How are kidney stones formed?

• A. Due to excess water not being reabsorbed
• B. When minerals crystallize in the urine
• C. When electrolytes become too concentrated
• D. All of the above

Correct answer: B

Rationale: Kidney stones are formed when minerals in the urine crystallize and stick together to form solid masses. Excess water not being reabsorbed (option A) does not directly contribute to kidney stone formation. Similarly, electrolytes becoming too concentrated (option C) is not a direct cause of kidney stone formation. The correct answer is B because the crystallization of minerals in the urine leads to the formation of kidney stones.
