1. The author's tone towards UBI can be described as

• A. Strongly supportive, advocating for its immediate implementation without reservations.
• B. Strongly critical, highlighting only the potential drawbacks and dismissing its benefits.
• C. Neutral and objective, presenting both sides of the argument without taking a stance.
• D. Cautiously optimistic, acknowledging both the potential and challenges while calling for further discussion.

Correct answer: D

Rationale: The passage acknowledges both positive and negative aspects of UBI, suggesting a cautious and balanced perspective, aligning with D.

2. What is the process by which the body reabsorbs water from the large intestine?

• A. Dehydration
• B. Osmosis
• C. Filtration
• D. Secretion

Correct answer: B

Rationale: Rationale: - Dehydration (Option A) refers to the condition of having insufficient water in the body, not the process of water reabsorption in the large intestine. - Osmosis (Option B) is the movement of water across a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration. In the large intestine, water is reabsorbed through osmosis to maintain the body's fluid balance. - Filtration (Option C) is a process where a liquid or gas passes through a filter to separate the components. It is not the primary mechanism for water reabsorption in the large intestine. - Secretion (Option D) is the release of substances from cells, but it is not the process by which the body reabsorbs water from the large intestine. Therefore, the correct process by which the body reabsorbs water from the large intestine is

3. Fertilization of the egg by sperm typically occurs in the:

• A. Ovary
• B. Fallopian tube
• C. Uterus
• D. Vagina

Correct answer: B

Rationale: The correct answer is B: Fallopian tube. Fertilization of the egg by sperm typically occurs in the fallopian tube. After ovulation, the egg travels through the fallopian tube where it can meet sperm for fertilization. The fallopian tube provides an ideal environment for fertilization to occur due to its proximity to the ovaries and the uterus. The other options, A: Ovary, C: Uterus, and D: Vagina, are not the typical sites for fertilization to take place. Therefore, the fallopian tube is the most appropriate location for the union of egg and sperm to form a zygote.

4. Which property of matter explains why ice floats on water?

• A. Viscosity
• B. Density
• C. Buoyancy
• D. Surface tension

Correct answer: c

Rationale: Buoyancy is the upward force exerted by a fluid (like water) on an object immersed in it. Ice floats on water because it is less dense than water, experiencing an upward force (buoyancy) greater than its weight.

5. The energy absorbed during a chemical reaction is called:

• A. Kinetic energy
• B. Potential energy
• C. Heat energy
• D. Endothermic energy

Correct answer: D

Rationale: Endothermic means "inward heat," indicating energy is absorbed during the reaction.

6. What is the name of the cartilage flap that covers the trachea during swallowing, preventing food from entering the airway?

• A. Epiglottis
• B. Glottis
• C. Larynx
• D. Pharynx

Correct answer: A

Rationale: The correct answer is A: Epiglottis. The epiglottis is a cartilage flap located at the base of the tongue that covers the trachea during swallowing. Its main function is to prevent food or liquid from entering the airway and instead directs them towards the esophagus. The glottis (option B) is the space between the vocal cords in the larynx, not a cartilage flap. The larynx (option C) is the voice box located in the throat, and the pharynx (option D) is the throat cavity connecting the mouth and the esophagus. Understanding the role of the epiglottis in protecting the airway during swallowing is crucial for maintaining proper respiratory function.
