1. What is the product of the decomposition of water?

• A. Hydrogen and oxygen
• B. Carbon dioxide
• C. Nitrogen and hydrogen
• D. Methane

Correct answer: A

Rationale: The correct answer is A: Hydrogen and oxygen. When water undergoes decomposition, it breaks down into hydrogen and oxygen gases through a process known as electrolysis. This reaction is represented by 2H₂O → 2H₂ + O₂. Choice B, carbon dioxide, is incorrect as it is not a product of water decomposition. Choice C, nitrogen and hydrogen, is incorrect as water decomposes into hydrogen and oxygen, not nitrogen. Choice D, methane, is incorrect as methane is not a product of water decomposition.

2. What is the probability of rolling a 3 on a six-sided die?

• A. 1/6
• B. 1/4
• C. 1/3
• D. 1/2

Correct answer: A

Rationale: The probability of rolling a specific number on a six-sided die is calculated by dividing the favorable outcomes (rolling a 3) by the total possible outcomes. In this case, there is 1 favorable outcome (rolling a 3) out of 6 total possible outcomes (numbers 1 to 6 on the die). Therefore, the probability of rolling a 3 is 1/6. Choice B (1/4), C (1/3), and D (1/2) are incorrect because they do not represent the correct calculation of the probability for rolling a 3 on a six-sided die.

3. What does Cast mean?

• A. A tool used for breaking bones
• B. Hard protective device applied to protect a broken bone
• C. A soft bandage
• D. An instrument used in surgery

Correct answer: B

Rationale: The correct answer is B. A cast is a hard protective device applied to protect a broken bone. Choice A is incorrect as a cast is not a tool used for breaking bones, but rather for supporting and protecting them. Choice C is incorrect as a cast is not a soft bandage but a rigid structure. Choice D is incorrect as a cast is not an instrument used in surgery, but a medical device used for bone support.

4. Tundra, savannas, grasslands, deserts, and rainforests are examples of what?

• A. Biomasses
• B. Biospheres
• C. Biodiversity
• D. Biomes

Correct answer: D

Rationale: Tundra, savannas, grasslands, deserts, and rainforests are examples of biomes. A biome is a large geographical area with similar climatic conditions and distinct flora and fauna. Each biome has its unique characteristics, such as temperature, precipitation levels, and types of vegetation, which define the ecosystem within that region. Biomasses refer to the total mass of living organisms in a given area, biospheres are the global ecological system integrating all living beings and their relationships, and biodiversity represents the variety of life forms in a specific habitat.

5. Which term refers to the surgical removal of an organ's contents?

• A. Excretion
• B. Evisceration
• C. Incision
• D. Reduction

Correct answer: B

Rationale: The correct answer is B, 'Evisceration.' Evisceration specifically means the surgical removal of an organ's contents. Choice A, 'Excretion,' is the process of eliminating waste products from the body and is not related to surgical procedures. Choice C, 'Incision,' refers to the act of cutting into the body, commonly done in surgeries but not specifically related to removing organ contents. Choice D, 'Reduction,' generally means to make something smaller or lessen its size, which is not the term used for the surgical removal of an organ's contents.
