English Grammar
1. Which sentence uses the word "literally" correctly?
- A. literally died laughing at that joke.
- B. He literally climbed a mountain of paperwork.
- C. Her eyes were literally sparkling with excitement.
- D. The house was literally haunted by ghosts.
Correct answer: B
Rationale: Option B uses "literally" to emphasize the magnitude of work, not to exaggerate a simple action.
2. You observe that plants in a greenhouse grow faster when exposed to red light compared to blue light. What is the next best step in your investigation?
- A. Increase the intensity of the blue light.
- B. Decrease the intensity of the red light.
- C. Grow plants in complete darkness.
- D. Grow plants exposed to both red and blue light at equal intensities.
Correct answer: D
Rationale: The next best step in the investigation would be to grow plants exposed to both red and blue light at equal intensities. This will help determine if the observed growth difference is due to the specific wavelength of light (red vs. blue) or if it is related to the intensity of light. By exposing plants to both red and blue light at equal intensities, you can compare their growth rates and determine if one wavelength has a greater effect on plant growth.
3. A ball is thrown upwards. Which of the following statements is TRUE about its potential energy and kinetic energy at the peak of its trajectory?
- A. Both potential and kinetic energy are zero.
- B. Potential energy is maximum and kinetic energy is minimum.
- C. Potential energy is minimum and kinetic energy is maximum.
- D. Both potential and kinetic energy remain constant.
Correct answer: B
Rationale: At the peak, the ball momentarily stops moving, minimizing kinetic energy. However, it's still at its highest point, maximizing its potential energy due to gravity.
4. What is the general formula for an alkyl halide?
- A. CnH2n
- B. CnH2n+2
- C. CnH2n-1X
- D. CnH2nO
Correct answer: C
Rationale: The general formula for an alkyl halide is \(C_nH_{2n-1}X\), where X represents a halogen (e.g., F, Cl, Br, I).
5. What is the medical term for a urinary tract infection (UTI)?
- A. Nephritis
- B. Cystitis
- C. Urethritis
- D. All of the above
Correct answer: D
Rationale: The correct answer is D, 'All of the above.' A urinary tract infection (UTI) can affect different parts of the urinary system. Nephritis refers to inflammation of the kidneys, cystitis refers to inflammation of the bladder, and urethritis refers to inflammation of the urethra. Therefore, all of these terms can be used to describe a UTI depending on which part of the urinary tract is affected. It's important to differentiate between these terms to accurately diagnose and treat UTIs.
6. Which of the following is an example of static friction?
- A. Sliding a heavy box across the floor
- B. A car moving around a curve
- C. Pushing a stationary object
- D. Braking a car to stop
Correct answer: c
Rationale: Static friction occurs when an object is at rest and prevents it from moving when a force is applied.
