1. If a theory is obsolete, what is true of it?

A. Up to date
B. Outdated
C. Innovative
D. Scientific

Correct answer: B

Rationale: The correct answer is B: 'Outdated.' When something is described as 'obsolete,' it means that it is outdated or no longer in use. Therefore, an obsolete theory is no longer current or relevant. Choices A, C, and D are incorrect because an obsolete theory is not considered up to date, innovative, or necessarily scientific; it is outdated and no longer relevant in its field.

2. Select the meaning of the word 'incidence' in the sentence: 'The incidence of smoking has decreased.'

A. Prestige
B. Occurrence
C. Glamour
D. Influence

Correct answer: B

Rationale: In this context, 'incidence' refers to the rate or frequency at which something happens, specifically the rate of occurrence of smoking. Therefore, 'Occurrence' is the correct answer. Choice A, 'Prestige,' is incorrect as it refers to reputation or esteem. Choice C, 'Glamour,' is also incorrect as it means attractiveness or charm. Choice D, 'Influence,' is not the best fit as it relates more to the capacity to have an effect on someone or something.

3. Select the word that means 'a violent seizure.'

A. revelation
B. nutrient
C. contraption
D. paroxysm

Correct answer: D

Rationale: 'Paroxysm' is the correct answer as it refers to a sudden, violent seizure or outburst. The other choices are incorrect because 'revelation' means a surprising and previously unknown fact, 'nutrient' refers to a substance that provides nourishment, and 'contraption' means a machine or device that is strange or unnecessarily complicated.

4. If a lump under the skin is palpable, what is true?

A. It is malignant.
B. It has burst.
C. It is warm.
D. It can be felt.

Correct answer: D

Rationale: If a lump under the skin is palpable, it means that it can be felt or touched. Palpable lumps can be detected by touch, which can lead to further evaluation or examination by a healthcare professional to determine the cause and appropriate treatment. The correct answer is 'D' because when a lump is palpable, it means it can be physically felt, indicating its presence under the skin. Choices A, B, and C are incorrect because the palpability of a lump does not automatically indicate malignancy, bursting, or warmth.

5. What does 'Fatal' mean?

A. Resulting in injury
B. Resulting in death

Correct answer: B

Rationale: The correct answer is B: 'Resulting in death.' The term 'Fatal' specifically means resulting in death. Choices A, C, and D are incorrect because 'Fatal' does not refer to resulting in injury, being dangerous, or being treatable.
