English Grammar
1. What is the meaning of the idiom "to bite off more than one can chew"?
- A. To be overly confident
- B. To take on more than one can handle
- C. To be easily discouraged
- D. To be meticulous in planning
Correct answer: B
Rationale: The idiom warns against undertaking a task exceeding one's capabilities.
2. Which hormone, produced by the thyroid gland, regulates calcium levels in the blood by enhancing calcium absorption in the intestines and reducing calcium loss in the kidneys?
- A. Calcitonin
- B. Parathyroid hormone (PTH)
- C. Thyroxine
- D. Insulin
Correct answer: a
Rationale: The correct answer is A: Calcitonin. Calcitonin is a hormone produced by the thyroid gland that plays a crucial role in regulating calcium levels in the blood. It works by enhancing calcium absorption in the intestines and reducing calcium loss in the kidneys. This helps to maintain the proper balance of calcium in the body. Parathyroid hormone (PTH) works in the opposite way, increasing calcium levels in the blood when they are low. Thyroxine is a hormone produced by the thyroid gland that regulates metabolism and growth, not calcium levels. Insulin is a hormone produced by the pancreas that regulates blood sugar levels, not calcium levels. Therefore, the correct hormone in this case is Calcitonin.
3. During photosynthesis, plants capture sunlight and convert water and carbon dioxide into glucose and oxygen. This is an example of a:
- A. Decomposition reaction
- B. Combustion reaction
- C. Synthesis reaction
- D. Double displacement reaction
Correct answer: C
Rationale: The correct answer is C: Synthesis reaction. During photosynthesis, plants combine water and carbon dioxide using sunlight to produce glucose and oxygen. In a synthesis reaction, two or more substances combine to form a more complex product. In this case, glucose and oxygen are synthesized from simpler molecules. A decomposition reaction involves breaking down a compound into simpler substances, which is not the case in photosynthesis. Combustion reactions involve the rapid reaction of a fuel with oxygen to produce heat and light, which is also not the process occurring in photosynthesis. Double displacement reactions involve the exchange of ions between two compounds to form new compounds, which is not the mechanism of photosynthesis. Therefore, the process described in the question aligns with a synthesis reaction.
4. A solution is considered saturated when...
- A. More solute can be dissolved
- B. The solvent starts to evaporate
- C. The solution becomes cloudy
- D. It reaches a specific temperature
Correct answer: B
Rationale: The correct answer is B: 'The solvent starts to evaporate.' A solution is considered saturated when the solvent can no longer dissolve any more solute at a given temperature. When the solvent starts to evaporate, it means that the solution is becoming more concentrated and reaching its saturation point. This is a key indicator of a saturated solution. The other options do not accurately describe the concept of a saturated solution, making them incorrect choices.
5. How do you spell the past participle of the verb "lie" (to recline)?
- A. lied
- B. lain
- C. lay
- D. lying
Correct answer: B
Rationale: The past participle of "lie" (to recline) is "lain," not "lied," which is the past tense.
6. The final sentence suggests that users should approach social media with a healthy dose of
- A. Enthusiasm and optimism about its potential for connection and engagement.
- B. Skepticism and critical thinking towards the information encountered online.
- C. Acceptance of its flaws and a passive reliance on its features for interaction.
- D. Indifference towards its impacts and an absence of any effort to manage its use.
Correct answer: B
Rationale: The emphasis on "critical thinking" and "skepticism" suggests the importance of approaching social media with a cautious and discerning mind, aligning with B
