1. What type of force opposes the motion of an object moving through a fluid (liquid or gas)?

• A. Gravitational force
• B. Tension force
• C. Viscous force
• D. Magnetic force

Correct answer: c

Rationale: Viscous force is the resistance experienced by an object moving through a fluid due to internal friction.

2. Based on the passage, the author most likely believes that

• A. Individual actions are insignificant in addressing climate change, and only large-scale initiatives matter.
• B. Adaptation to the changing climate is impossible, and societal collapse is inevitable.
• C. Transitioning to renewable energy and sustainable practices offers hope for mitigating climate change.
• D. The scientific evidence for climate change is unreliable, and further research is needed before taking action.

Correct answer: C

Rationale: The focus on global efforts, renewable energy, and sustainable practices suggests an optimistic outlook on mitigating climate change, aligning with C.

3. Bile, stored in the gallbladder, aids in the digestion of:

• A. Carbohydrates
• B. Proteins
• C. Fats
• D. Vitamins

Correct answer: C

Rationale: The correct answer is C: "Fats." Bile, produced by the liver and stored in the gallbladder, plays a crucial role in the digestion and absorption of fats. When you consume fatty foods, bile is released into the small intestine to help break down the fats into smaller droplets, making it easier for enzymes to digest them. This process allows the body to absorb essential fatty acids and fat-soluble vitamins. Carbohydrates are mainly digested by enzymes like amylase in the mouth and small intestine, while proteins are broken down by enzymes like pepsin and trypsin. Vitamins are not directly digested by bile but are absorbed along with fats in the small intestine. Therefore, the correct answer is C, as bile aids in the digestion of fats.

4. An object is thrown at an angle. Which of the following forces acts HORIZONTALLY on the object during its flight?

• A. Gravitational force
• B. Normal force from the ground
• C. Air resistance
• D. The force of throwing

Correct answer: C

Rationale: Gravitational force acts downwards, normal force is perpendicular to motion at the launch point, and the throwing force is gone after release. Only air resistance acts continuously to oppose horizontal motion.

5. What is the general formula for an alcohol?

• A. CnH2n
• B. CnH2n+2
• C. CnH2n-1
• D. CnH2nO

Correct answer: D

Rationale: The general formula for an alcohol is \(C_nH_{2n}O\), indicating the presence of a hydroxyl group (-OH).

6. Which of the following factors can contribute to erectile dysfunction in males?

• A. Diabetes
• B. Cardiovascular disease
• C. Neurological disorders
• D. All of the above

Correct answer: D

Rationale: The correct answer is D, 'All of the above.' Erectile dysfunction in males can be caused by various factors including diabetes, cardiovascular disease, and neurological disorders. Diabetes can lead to nerve damage and reduced blood flow, impacting erectile function. Cardiovascular disease can restrict blood flow to the penis, affecting erections. Neurological disorders can disrupt the signals between the brain and the reproductive system, interfering with the ability to achieve or maintain an erection. Therefore, all of these factors can contribute to erectile dysfunction in males.
