1. If a dice is rolled, what is the probability of getting an even number?

• A. 16%
• B. 33%
• C. 66%
• D. 50%

Correct answer: D

Rationale: When rolling a standard six-sided die, there are three even numbers (2, 4, 6) out of a total of six possible outcomes (1, 2, 3, 4, 5, 6). The probability of rolling an even number can be calculated as the number of favorable outcomes (3) divided by the total number of outcomes (6), which equals 3/6 = 50%. Therefore, the correct answer is D. Choice A (16%) is incorrect because it does not represent the probability of rolling an even number. Choice B (33%) is incorrect as it does not reflect the correct probability. Choice C (66%) is incorrect as well since it overestimates the probability.

2. Select the correct definition of the word 'prognosis' in the sentence: 'The doctor’s prognosis gave the patient reason to feel optimistic.'

• A. Instructions
• B. Estimate
• C. Behavior
• D. Outcome statement

Correct answer: D

Rationale: In the context provided, 'prognosis' refers to a doctor's prediction or statement about the likely outcome of a disease or condition. This makes 'Outcome statement' the correct choice. 'Instructions' (A) are not related to prognosis. 'Estimate' (B) is a rough calculation or approximation, not a prediction of an outcome. 'Behavior' (C) refers to actions, conduct, or manner of an individual, which is not the meaning of 'prognosis' in this sentence.

3. Which of the following organelles is responsible for producing ATP in cells?

• A. Nucleus
• B. Mitochondrion
• C. Chloroplast
• D. Lysosome

Correct answer: B

Rationale: The correct answer is 'Mitochondrion.' Mitochondria are known as the powerhouse of the cell and are responsible for producing ATP, the energy currency of the cell. The nucleus is responsible for storing genetic material and controlling cell activities, not for ATP production. Chloroplasts are found in plant cells and are responsible for photosynthesis, not ATP production. Lysosomes are involved in digestion and waste removal, not ATP production.

4. Which of the following processes represents a different level of defense compared to the others?

• A. A low pH in the stomach
• B. Cilia present in the trachea
• C. Body cells recognizing a pathogen
• D. Mucus present in the nasal cavity

Correct answer: C

Rationale: Among the listed processes, low pH in the stomach, cilia in the trachea, and mucus in the nasal cavity serve as physical barriers that form the first line of defense against pathogens. These barriers work to block pathogens from entering the body. On the other hand, body cells recognizing a pathogen involves the immune response, which operates at a different level of defense. This process is part of the adaptive immune response, where the body's immune cells identify, target, and eliminate specific pathogens to provide a specialized defense after the pathogens have breached the physical barriers. Therefore, body cells recognizing a pathogen represent a different level of defense compared to the other listed processes.

5. Which statement from the passage on Voice is a fact rather than an opinion?

• A. One of the worst voice qualities is harshness.
• B. Harsh voice qualities come from tension in the throat.
• C. Your voice will sound unpleasant if it is shrill or grating.
• D. Because tension occurs in higher-pitched voices, women tend to have shriller voices than men.

Correct answer: B

Rationale: The correct answer is B. The fact that harsh voice qualities come from tension in the throat is a verifiable statement based on a scientific explanation provided in the passage. This statement is not subject to personal interpretation or judgment. Choice A is an opinion as it categorizes harshness as one of the worst voice qualities, which is subjective. Choice C is also an opinion as it describes how a voice will sound based on subjective terms like 'unpleasant.' Choice D is an opinion as it makes a generalized statement linking higher-pitched voices with shriller voices in women, which can vary widely among individuals.
