1. Knitting is my favorite hobby... Which of the following sentences does not fit with the rest of the paragraph above?

• A. There are other benefits of knitting, too.
• B. The repetition of stitch after stitch is so relaxing.
• C. A ball of wool holds so much potential and is also a sustainable resource.
• D. It helped me.

Correct answer: C

Rationale: The sentence about the ball of wool being a sustainable resource introduces a new idea that doesn't align with the other ideas in the paragraph, which focus on relaxation and health benefits. Choices A, B, and D all relate to the positive aspects and personal experience with knitting, which are in line with the paragraph's context. Choice A expands on the benefits of knitting, choice B highlights the relaxing nature of the activity, and choice D indicates a personal benefit obtained from knitting.

2. What is the result of dividing 8 by 4?

• A. 2
• B. 4
• C. 6
• D. 8

Correct answer: A

Rationale: To find the result of dividing 8 by 4, we divide 8 by 4, which equals 2. Choice B (4) is incorrect because it is the divisor, not the result of the division. Choice C (6) is incorrect as it is not the correct quotient. Choice D (8) is incorrect as it is the dividend, not the result of the division.

3. Which of the following is the main organ responsible for producing enzymes?

• A. Liver
• B. Pancreas
• C. Stomach
• D. Small intestine

Correct answer: B

Rationale: The main organ responsible for producing enzymes is the pancreas. Enzymes are proteins that act as biological catalysts to speed up chemical reactions in the body. The pancreas produces and releases digestive enzymes that help break down carbohydrates, proteins, and fats in the small intestine to aid in the digestion and absorption of nutrients. While the liver also plays a role in producing bile, which helps in the digestion and absorption of fats, the primary organ responsible for producing enzymes is the pancreas. The stomach produces gastric juices containing hydrochloric acid and pepsin to help break down food, but it is not the primary organ for enzyme production. The small intestine is where most nutrient digestion and absorption occur; however, it receives enzymes from organs like the pancreas rather than producing them itself.

4. What is the process by which decomposers break down organic matter?

• A. Photosynthesis
• B. Bioremediation
• C. Decomposition
• D. Nitrification

Correct answer: C

Rationale: A) Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy to produce glucose from carbon dioxide and water. This process is not related to the breakdown of organic matter by decomposers. B) Bioremediation is the use of living organisms to clean up contaminated environments. While it involves the use of microorganisms to break down pollutants, it is not specifically focused on breaking down organic matter. C) Decomposition is the process by which decomposers such as bacteria, fungi, and other organisms break down organic matter into simpler substances. This process is essential for nutrient recycling in ecosystems. D) Nitrification is the biological oxidation of ammonia or ammonium to nitrite followed by the oxidation of nitrite to nitrate by nitrifying bacteria. This process is part of the nitrogen cycle and is not directly related to the breakdown of organic matter.

5. Which of the following is NOT a common location for lymph nodes?

• A. Groin
• B. Armpit
• C. Neck
• D. Liver

Correct answer: D

Rationale: The correct answer is 'D: Liver.' The liver is not a common location for lymph nodes. Lymph nodes are small, bean-shaped structures distributed throughout the body, including common sites like the groin, armpit, and neck. They play a crucial role in the immune system by filtering lymph fluid and trapping harmful substances, aiding the body in defending against infections and diseases. The liver, on the other hand, is an organ responsible for various functions like detoxification, metabolism, and storage, but it does not house lymph nodes.
