Reading
1. Based on the passage, which statement is MOST likely to be true about the author's stance on social media?
- A. It should be completely banned due to its overwhelmingly negative impact.
- B. It can be a valuable tool but needs stricter regulations to address emerging issues.
- C. Its benefits outweigh its drawbacks, and concerns about its use are exaggerated.
- D. Technology alone cannot solve the problems associated with social media use.
Correct answer: B
Rationale: The emphasis on critical thinking and responsible online behavior suggests an acknowledgment of social media's potential while advocating for addressing its downsides, aligning with B.
2. Which of the following is a unit of work and energy?
- A. Pascal (Pa)
- B. Kilowatt-hour (kWh)
- C. Coulomb (C)
- D. Tesla (T)
Correct answer: b
Rationale: Kilowatt-hour is a unit used to measure both work and energy, especially in the context of electricity consumption.
3. Which hormone, produced by the adrenal glands, prepares the body for a "fight or flight" response by increasing heart rate, dilating airways, and mobilizing energy stores?
- A. Cortisol
- B. Aldosterone
- C. Epinephrine
- D. Insulin
Correct answer: c
Rationale: The correct answer is C: Epinephrine. Epinephrine, also known as adrenaline, is the hormone produced by the adrenal glands that prepares the body for a 'fight or flight' response. It increases heart rate to pump more blood to muscles, dilates airways to improve oxygen intake, and mobilizes energy stores to provide immediate fuel for physical activity. Cortisol is a hormone involved in stress response and metabolism regulation, but it does not directly trigger the rapid physiological changes associated with 'fight or flight.' Aldosterone regulates salt and water balance, while insulin regulates blood sugar levels, neither of which are directly involved in preparing the body for a rapid response to danger or stress.
4. A study finds a link between increased sugar intake and obesity. Does this confirm sugar causes obesity?
- A. Yes, the study definitively proves causation.
- B. No, correlation does not equal causation, other factors might be involved.
- C. We need more research to isolate the specific role of sugar.
- D. This only applies to people with genetic predispositions to obesity.
Correct answer: C
Rationale: Correlation suggests a link, but other factors might contribute. Further research is needed to establish the direction and strength of any causal relationship.
5. What is the most effective way to ensure clarity and conciseness in your writing?
- A. Using complex sentence structures and passive voice.
- B. Avoiding unnecessary repetition and redundant words.
- C. Replacing simple words with more sophisticated synonyms.
- D. Adding flowery introductions and lengthy conclusions.
Correct answer: B
Rationale: Concise writing eliminates unnecessary words and uses active voice to express ideas directly and clearly.
6. What is the coefficient of oxygen in the balanced chemical equation for the combustion of methane (CH4)?
- A. 1
- B. 2
- C. 3
- D. 4
Correct answer: b
Rationale: The balanced equation is CH4 + 2O2 → CO2 + 2H2O, so the coefficient of oxygen is 2.
