English Grammar
1. Which sentence uses the modal verb "should" correctly?
- A. You should have studied harder for the exam.
- B. I should be going now.
- C. She said she should have taken a different route.
- D. They should be arriving any minute now.
Correct answer: B
Rationale: Option B conveys an intention or expectation regarding the present or near future.
2. In the process of osmosis, the solvent moves from an area of...
- A. Low solute concentration to high solute concentration
- B. Hotter solution to colder solution
- C. Colder solution to hotter solution
- D. High solute concentration to low solute concentration
Correct answer: D
Rationale: In osmosis, solvent molecules move across a semi-permeable membrane from an area of low solute concentration to high solute concentration. This movement is driven by the desire to equalize the concentration of solutes on both sides of the membrane. As a result, option A is the correct answer because the solvent will naturally flow towards the area with a higher concentration of solutes in order to balance the concentrations on both sides of the membrane. Options B and C are incorrect as osmosis is not influenced by temperature differences. Option D is incorrect as the solvent does not move towards areas of high solute concentration in osmosis.
3. Which force opposes the relative motion between surfaces in contact?
- A. Tension force
- B. Frictional force
- C. Gravitational force
- D. Magnetic force
Correct answer: b
Rationale: Friction is the force that opposes motion between surfaces in contact.
4. Which of the following is a risk factor for developing kidney stones?
- A. Consuming a diet rich in fruits and vegetables
- B. Maintaining adequate hydration with water
- C. Having a family history of kidney stones
- D. Regularly engaging in moderate exercise
Correct answer: C
Rationale: Having a family history of kidney stones is a risk factor for developing them because genetics play a role in kidney stone formation. Individuals with a family history are more likely to inherit genetic factors that increase the likelihood of developing kidney stones. While consuming a diet rich in fruits and vegetables, maintaining adequate hydration with water, and regularly engaging in moderate exercise are generally healthy habits that can help prevent kidney stones, they are not direct risk factors for developing them. Therefore, option C, having a family history of kidney stones, is the correct answer.
5. What is the waste product of protein digestion?
- A. Glucose
- B. Amino acids
- C. Fatty acids
- D. Ammonia
Correct answer: D
Rationale: Rationale: Protein digestion involves breaking down proteins into their constituent amino acids. During this process, the waste product produced is ammonia. Ammonia is a toxic compound that needs to be converted into urea in the liver and then excreted by the kidneys in the form of urine. Glucose is a product of carbohydrate digestion, amino acids are the building blocks of proteins, and fatty acids are the end products of fat digestion.
6. The diaphragm is a dome-shaped muscle that plays a crucial role in breathing. When it contracts, what happens?
- A. Air is expelled from the lungs.
- B. The lungs expand to allow air intake.
- C. The vocal cords vibrate to produce sound.
- D. The trachea narrows to control airflow.
Correct answer: B
Rationale: The diaphragm is a dome-shaped muscle located beneath the lungs. When it contracts, it moves downward, creating more space in the chest cavity. This downward movement of the diaphragm allows the lungs to expand, which lowers the air pressure inside the lungs. As a result, air from the outside rushes in to equalize the pressure, leading to inhalation. Therefore, when the diaphragm contracts, it facilitates the intake of air into the lungs, making option B, 'The lungs expand to allow air intake,' the correct answer.
