1. A honeycomb cell has six equal sides, each measuring 8mm. What is its perimeter?

• A. 32mm
• B. 40mm
• C. 48mm
• D. 56mm

Correct answer: C

Rationale: To find the perimeter of a shape with equal sides, you multiply the length of one side by the number of sides. In this case, the honeycomb cell has 6 sides, each measuring 8mm. Therefore, the perimeter is calculated as perimeter = number of sides * side length = 6 * 8mm = 48mm. Choices A, B, and D are incorrect because they do not correctly calculate the total length around the honeycomb cell with six sides.

2. What does ONEROUS mean?

• A. Easy
• B. Burdensome
• C. Interesting
• D. Relaxing

Correct answer: B

Rationale: The correct answer is B, 'Burdensome.' The term 'onerous' is used to describe something that is burdensome, oppressive, or difficult to deal with. Choices A, C, and D are incorrect because 'easy,' 'interesting,' and 'relaxing' do not convey the same meaning as 'onerous.'

3. Select the phrase that will make the following sentence grammatically correct. Before I had finished supper, James ___________.

• A. is texting me on my cell phone
• B. had texted me on my cell phone
• C. texts me on my cell phone
• D. texting me on my cell phone

Correct answer: B

Rationale: The sentence starts with 'Before I had finished supper,' indicating that the action of James texting you on your cell phone had occurred before the completion of another past action (finishing supper). The past perfect tense 'had texted' is used to express an action that happened before another action in the past, making the sentence grammatically correct. Choice A is incorrect because it uses the present continuous tense, which is not suitable for indicating an action that occurred before finishing supper. Choice C is incorrect as it uses the simple present tense, which does not convey the sequence of events correctly. Choice D is incorrect as it presents the present continuous tense, which is not appropriate for the context of the sentence.

4. What is the value of x in the ratio and proportion 0.1:10=x:400?

• A. 5
• B. 4
• C. 50
• D. 25

Correct answer: B

Rationale: To solve the proportion 0.1:10=x:400, first, simplify the left side to 1:100. Then, set up the proportion as 1:100=x:400. Cross multiply to get x = 4. Therefore, the correct answer is B. Choice A (5) is incorrect because it does not match the calculated value of x. Choice C (50) is incorrect as it is not the result of solving the proportion provided. Choice D (25) is incorrect as it does not align with the correct calculation of x.

5. What is the normal pH of human arterial blood?

• A. 6.8
• B. 7.4
• C. 7.9
• D. 8.2

Correct answer: B

Rationale: The normal pH of human arterial blood is approximately 7.4. This slightly alkaline pH is crucial for the proper functioning of enzymes and biochemical processes in the body. Any significant deviation from this pH level can result in serious health issues such as acidosis or alkalosis. Choice A (6.8) is incorrect as it is lower than the normal pH of arterial blood, indicating acidity. Choice C (7.9) and Choice D (8.2) are incorrect as they are higher than the normal pH of arterial blood, indicating alkalinity.
