3. Which of the following is NOT mentioned in the passage?
Answer: D
Why the British government refused Daylight Savings Time is NOT mentioned in the passage.
The passage discusses various aspects of Daylight Savings Time (DST), including its history and implementation, but it does not provide specific reasons for the British government's refusal of the initial proposal for DST.
A) The cause of jet lag
The passage clearly mentions that moving suddenly from one time zone to another can cause jet lag, leading to feelings of tiredness and disrupted sleep. Therefore, this option is incorrect as it is explicitly discussed in the text.
B) The amount of daylight at the tropics
The passage describes that countries located in the tropics receive a consistent amount of daylight throughout the year, with the Sun rising at 6 AM and setting at 6 PM. This information is provided in the extract, making this option incorrect as well.
C) Why the time readjustment will happen
The passage explains that the clock readjustment occurs to maximize daylight exposure during different seasons. This rationale is directly linked to the practice of Daylight Savings Time. Thus, this option is also incorrect because it is mentioned in the text.
D) Why the British government refused Daylight Savings Time
The passage states that the British government deemed the proposal unnecessary but does not elaborate on the specific reasons behind this decision. Therefore, this option is correct since it is not detailed in the extract.
Conclusion
Option D is the only choice that is not mentioned in the passage, as it lacks any elaboration on the reasons for the British government's refusal of Daylight Savings Time. In contrast, the other options are all supported by the information provided in the text, confirming their relevance and correctness.
