India needs to manage daylight much better than it does. Maximising it is also a good place to start to be more energy efficient. Not using daylight properly comes at a cost - $4.1 billion, or 0.2% of GDP, according to a Cornell study, in addition to health impacts. Experts have suggested multiple time zones in India, perhaps reverting to the pre-1947 system of two time zones, as proposed by the Council of Scientific and Industrial Research (CSIR)- National Physical laboratory, India's official time keeper. But considering the huge investments required, as well as the logistical exercise of coordination, make this idea unattractive. Daylight savings is a more practical option.
Daylight savings time, or summertime is the system of advancing clock by an hour to get more light out of the day. This would permit using the extra hour of daylight in summer months between March and October. And it would avoid using lights on winter mornings because the sun rises later. This system will be particularly useful in the eastern and northeastern part of the country. To further maximise use of daylight, a shift away from uniform opening hours at workplaces can be advantageous. The sun sets roughly 90 minutes later in western parts of the country than in the eastern parts. In northeast and eastern states, establishments could begin work an hour earlier than elsewhere. It would allow people here to match their working hours to environmental cues, while giving a head start to others elsewhere.
Advancing time to maximise use of daylight has energy saving potential, which will significantly alter energy usage, cut down India's carbon footprint and help leverage the natural resource of sunlight. It's about maximising hay when the sun shines.
Given below are two statements:
Statement I: Daylight savings time would permit using the extra hour of daylight from March to October.
Statement II: Uniform opening hours at all workplaces will maximize use of daylight.
In the light of the above statements, choose the correct answer from the options given below:
Answer: C. Statement I is true but Statement II is false — CONCEPTA statement-based reading-comprehension item is solved by checking each statement independently against the passage. A statement is supported only when…
- A.
Both Statement I and Statement II are true
- B.
Both Statement I and Statement II are false
- C.
Statement I is true but Statement II is false
- D.
Statement I is false but Statement II is true
Show answer & explanation
Correct answer: C
CONCEPT
A statement-based reading-comprehension item is solved by checking each statement independently against the passage. A statement is supported only when its meaning agrees with the text; shared vocabulary alone is not enough.
APPLICATION
The passage explicitly says that daylight saving time would permit use of an extra hour of daylight between March and October. This directly supports Statement I.
The passage recommends a shift away from uniform workplace opening hours and says that establishments in eastern and northeastern states could start an hour earlier. This contradicts Statement II, which claims that uniform opening hours would maximise daylight use.
CROSS-CHECK
The two statements must not be judged as a pair until each has been checked separately. Statement I repeats the passage’s time window, whereas Statement II reverses the passage’s recommendation about workplace schedules.
RESULT
Therefore, Statement I is true and Statement II is false.
