1. The doctor said he wanted to try other things before attempting an __________ procedure.

• A. Internal
• B. Painful
• C. Experimental
• D. Expensive

Correct answer: C

Rationale: The term 'invasive' refers to a procedure that involves entering the body, usually with a medical instrument or device. In the context provided, the doctor wants to try other non-invasive or less invasive options before resorting to an invasive procedure. 'Experimental' means untested or not yet proven to be effective, which aligns with the idea of exploring alternative methods before considering a more invasive approach. Choices A, B, and D are incorrect because they do not relate to the context of trying alternative procedures that are different from invasive ones.

2. Which verb form best completes the sentence?

• A. Going
• B. Go
• C. Have
• D. Having

Correct answer: D

Rationale: The correct answer is 'Having.' In the sentence 'I am looking forward to having my birthday party next week,' 'having' is the correct present participle form of the verb 'have' to indicate an anticipated event. Choice A 'Going' is incorrect as it does not match the structure of the sentence. Choice B 'Go' is incorrect as it is the base form of the verb and does not fit grammatically. Choice C 'Have' is incorrect as it is the base form and does not convey the future action in the sentence.

3. A farmer wants to plant trees around the outside boundaries of his rectangular field with dimensions of 650 meters × 780 meters. Each tree requires 5 meters of free space all around it from the stem. How many trees can he plant?

• A. 572
• B. 568
• C. 286
• D. 282

Correct answer: C

Rationale: To determine the number of trees, reduce the field dimensions by 10 meters (5 meters of space on each side). The effective area is 640 meters × 770 meters. Each tree occupies 10 meters × 10 meters. Dividing the effective area by the space for each tree gives: (640 × 770) ÷ (10 × 10) = 286 trees. Choice A, B, and D are incorrect because they do not consider the reduction in field dimensions and the space required for each tree.

4. Which of the following is true of Glycolysis?

• A. It requires the absence of Oxygen
• B. It occurs in the presence of Oxygen
• C. It is the final step of fermentation
• D. It is the final step of anaerobic respiration

Correct answer: B

Rationale: Glycolysis is the first step in cellular respiration and can occur in both aerobic (presence of oxygen) and anaerobic (absence of oxygen) conditions. In aerobic respiration, glycolysis takes place in the presence of oxygen and continues with the Krebs cycle and the electron transport chain. So, glycolysis does not require the absence of oxygen but can occur in its presence as part of the overall process of aerobic respiration. Choice A is incorrect because glycolysis can occur in the presence of oxygen. Choice C is incorrect because glycolysis is not the final step of fermentation; it is the initial step. Choice D is incorrect because glycolysis is not the final step of anaerobic respiration; it is the first step, followed by further processes to complete anaerobic respiration.

5. Which organelle contains the genetic material of the cell?

• A. Golgi apparatus
• B. Ribosome
• C. Endoplasmic reticulum
• D. Nucleus

Correct answer: D

Rationale: The correct answer is 'D: Nucleus.' The nucleus is the organelle that contains the cell's genetic material, which is the DNA. The genetic material in the nucleus controls the cell's activities and plays a crucial role in inheritance. Choices A, B, and C are incorrect because the Golgi apparatus is involved in modifying, sorting, and packaging of proteins; ribosomes are involved in protein synthesis; and endoplasmic reticulum is involved in protein and lipid synthesis and transportation, but none of them contain the genetic material of the cell.
