An infection (Choice D) is the invasion and multiplication of microorganisms in body tissues.

Correct Answer: C

Rationale: The correct answer is C: 'Gradual.' In the context provided, 'insidious' describes a disease that develops slowly and harmfully over time, without being easily noticed. Choices A, B, and D are incorrect. 'Sudden' (choice A) means something happening quickly or unexpectedly, 'Suffer' (choice B) means to experience pain or hardship, and 'Graduate' (choice D) means to successfully complete a process or course of study, none of which capture the intended meaning of 'insidious' in this context.

Correct Answer: C

Rationale: The correct answer is 'Democratic.' A 'Democratic' leadership style involves the leader being open to new ideas and thoughts from the group and encourages group participation in decision-making. This style promotes collaboration, communication, and inclusivity in decision-making processes. 'Laissez-faire' leadership is characterized by a hands-off approach with minimal guidance or direction. 'Autocratic' leadership is where the leader makes decisions without much input from the group. 'Direct' leadership is not a widely recognized leadership style in this context.

Correct Answer: A

Rationale: The correct answer is A: 'Undesirable.' In this context, 'adverse' means harmful or undesirable, specifically referring to the negative side effects experienced from the medication. Choice B, 'Frequent,' is incorrect as 'adverse' does not imply how often the side effects occur but rather their nature. Choice C, 'Noticeable,' is incorrect as 'adverse' does not necessarily mean that the side effects are easily noticeable, but rather that they are harmful. Choice D, 'Constant,' is incorrect as 'adverse' does not indicate that the side effects are continuous but rather that they are negative.

Correct Answer: C

Rationale: The correct answer is C because the environment refers to the surroundings or conditions in which a person, animal, or plant lives or operates, encompassing both internal and external factors. Choices A, B, and D are incorrect as they do not accurately define the concept of 'environment.' Choice A is too broad and does not specifically address the components of an environment. Choice B is vague and does not capture the entirety of what an environment entails. Choice D is limited in scope, focusing solely on a home environment rather than the broader concept of environment.
