1. What is the result of adding 5 2/9 and 1 2/9?

• A. 6 4/9
• B. 7 5/9
• C. 7
• D. 5 2/9

Correct answer: A

Rationale: To add mixed numbers with fractions, first add the whole numbers together: 5 + 1 = 6. Then add the fractions: 2/9 + 2/9 = 4/9. Combining the whole number and the fraction parts gives 6 4/9. Therefore, the correct answer is 6 4/9. Choice B (7 5/9) is incorrect as the fractions were not added correctly. Choice C (7) is incorrect as it does not account for the fractions. Choice D (5 2/9) is one of the original numbers and not the sum of both.

2. Select the word or phrase that makes the following sentence grammatically correct: I was extremely surprised ___________ of her dismissal from the staff.

• A. learning
• B. to learn
• C. of learning
• D. have learned

Correct answer: B

Rationale: The correct phrase to use with 'surprised' in this sentence is 'to learn.' In this context, 'to learn' functions as an infinitive to indicate the purpose or reason for the surprise. 'Learning' (Choice A) is incorrect as it doesn't serve as an infinitive in this sentence. 'Of learning' (Choice C) is incorrect as it doesn't provide the correct structure needed in the sentence. 'Have learned' (Choice D) is incorrect because the verb tense does not match the context of the sentence.

3. What is the oxidation state of the potassium ion in the compound KCl?

• A. +1
• B. -1
• C. +2
• D. -2

Correct answer: A

Rationale: In the compound KCl (potassium chloride), potassium is in Group 1 of the periodic table, which means it has a valence electron of 1. Chlorine is in Group 17 and gains one electron to achieve a stable electron configuration by forming an ionic bond with potassium. As a result, the potassium ion in KCl has a +1 oxidation state. Therefore, the correct answer is +1. Choices B, C, and D are incorrect as they do not reflect the oxidation state of the potassium ion in KCl.

4. Which of the following epithelial types is correctly matched with its major function?

• A. Simple squamous epithelium – diffusion
• B. Stratified squamous epithelium – protection
• C. Stratified squamous epithelium – diffusion
• D. Simple columnar epithelium – secretion or absorption

Correct answer: D

Rationale: The correct answer is D. Simple columnar epithelium is indeed primarily responsible for secretion and absorption due to its tall shape and presence of microvilli, which increase surface area for these functions. Simple squamous epithelium is mainly involved in diffusion, allowing for the exchange of gases or nutrients. Stratified squamous epithelium functions more for protection against mechanical stress and pathogens, as it forms a tough, protective barrier due to its many layers.

5. What is the result of dividing 40.3 by 4.8?

• A. 7.5
• B. 8.4
• C. 6.2
• D. 9.1

Correct answer: B

Rationale: To divide 40.3 by 4.8, you perform the calculation: 40.3 ÷ 4.8 ≈ 8.4. Therefore, the correct answer is 8.4. Choice A (7.5) is incorrect as it is the result of dividing 40.3 by 5.4. Choice C (6.2) is incorrect as it is the result of dividing 40.3 by 6.5. Choice D (9.1) is incorrect as it is the result of dividing 40.3 by 4.4.
