English Grammar

1. Which sentence uses the passive voice correctly?

Correct answer: A

Rationale: Option a clearly identifies the object (letter) acted upon and the agent (Mary) performing the action in the passive voice.

2. Which property of a wave remains constant when it crosses a boundary between two different media?

Correct answer: d

Rationale: The speed of a wave remains constant when it crosses a boundary between two different media, although its direction may change.

3. What is the name of the muscle responsible for pumping blood throughout the body?

Correct answer: D

Rationale: The correct answer is D: Cardiac muscle. The cardiac muscle, also known as the heart muscle, is responsible for pumping blood throughout the body. Unlike voluntary muscles like the bicep, tricep, and deltoid, the cardiac muscle is involuntary and works continuously to pump blood to all parts of the body. It is crucial for maintaining circulation and delivering oxygen and nutrients to tissues. Understanding the role of the cardiac muscle in the circulatory system is essential for grasping the importance of heart health and overall well-being.

4. A table top has dimensions of 75cm by 50cm. What is its perimeter if opposite sides are equal?

Correct answer: B

Rationale: Rationale: - Given that the table top has dimensions of 75cm by 50cm. - Since opposite sides are equal, the table top can be divided into two pairs of equal sides: 75cm and 50cm. - To find the perimeter, we add up all four sides: 75cm + 50cm + 75cm + 50cm = 250cm. - However, since opposite sides are equal, we only need to consider two sides: 75cm + 50cm = 125cm. - Therefore, the perimeter of the table top is 125cm + 125cm = 150cm. - Hence, the correct answer is B) 150cm.

5. Simple columnar epithelium lining the small intestine is crucial for:

Correct answer: C

Rationale: The correct answer is C: Absorption. The simple columnar epithelium lining the small intestine is crucial for absorption due to its structure and function. It has microvilli that increase the surface area available for nutrient absorption. This epithelium also contains specialized cells like goblet cells that secrete mucus to protect the lining and aid in the movement of materials. Movement (choice A) is more related to muscle tissue rather than epithelial tissue. Support (choice B) is usually provided by connective tissue rather than epithelial tissue. Insulation (choice D) is not a function of the simple columnar epithelium in the small intestine.

6. The resolution of an optical instrument, like a microscope, refers to its ability to distinguish between:

Correct answer: D

Rationale: The resolution of an optical instrument, such as a microscope, is its ability to distinguish between very close, nearly identical objects. This means that the instrument can differentiate between two points that are close together and appear almost as one. A higher resolution allows for clearer and sharper images by minimizing the blurring effect that occurs when objects are close together. Options A, B, and C do not directly relate to the concept of resolution in optical instruments. Therefore, option D is the correct answer as it best describes what resolution entails in this context.
