1. The three main types of muscle tissue in the human body are:

A. Smooth, cardiac, and voluntary skeletal
B. Smooth, skeletal, and involuntary cardiac
C. Voluntary smooth, cardiac, and skeletal
D. Striated, non-striated, and epithelial

Correct answer: A

Rationale: The correct answer is A: Smooth, cardiac, and voluntary skeletal. Smooth muscle is found in the walls of internal organs and blood vessels, cardiac muscle makes up the heart, and voluntary skeletal muscle is attached to the bones and responsible for movement. Choice B is incorrect because cardiac muscle is involuntary, not voluntary. Choice C is incorrect because smooth muscle and cardiac muscle are involuntary, not voluntary. Choice D is incorrect because 'striated' and 'non-striated' refer to the appearance of muscle fibers, not the main types of muscle tissue in the body.

2. What property of a substance refers to its ability to be drawn into thin wires?

A. Conductivity
B. Ductility

3. Identify the antonym of the word "pensive":

A. joyous

4. A medication must be taken twice daily, 12 hours apart. If the first dose is at 8:00 AM, what is the most convenient time for the second dose to avoid disrupting sleep?

A. 4:00 PM
B. 6:00 PM
C. 8:00 PM
D. 10:00 PM

Correct answer: B

Rationale: Rationale: To take the medication 12 hours apart from the first dose at 8:00 AM, the second dose should be taken at 8:00 PM. However, to avoid disrupting sleep, it is recommended to take the second dose a bit earlier. Taking the second dose at 6:00 PM ensures that the medication is still being taken 12 hours apart while allowing for a buffer before bedtime to avoid any potential disruptions to sleep.

Correct answer: C

Rationale: The passage highlights the mutually beneficial relationship between smart grids and renewables, with both working together to optimize integration.

6. The study of fungi is known as:

A. Virology
B. Mycology

Fungi are a separate kingdom of organisms that include yeasts, molds, and mushrooms. C) Bacteriology is the study of bacteria, not fungi.
