Q. Passage-2
The history of renewable energy suggests there is a steep learning curve, meaning that, as more is produced, costs fall rapidly because of economies of scale and learning by doing. The firms’ green innovation is path-dependent: the more a firm does, the more it is likely to do in the future. The strongest evidence for this is the collapse in the price of solar energy, which became about 90% cheaper during the 2010s, repeatedly beating forecasts. Moving early and gradually gives economies more time to adjust, allowing them to reap the benefits of path-dependent green investment without much disruption. A late, more chaotic transition is costlier.
Q.8) What comes at X and Y respectively in the following sequence? January, January, December, October, X, March, October, Y, September
Answer: B
Notes:
Exp) Option b is the correct answer
Given sequence is:
January, January, December, October, X, March, October, Y, September
Consider the table given below:
Upon closer introspection we find that in the sequence the months move backwards in the order of 0,1,2,3 so on.
- For instance, January coming after January indicates a movement of 0 months
- December coming after January indicates a backward movement of 1 month from January
- Similarly, October is the second month from December when seen in the backward direction.
- Next, we need to find the third month from October in the backward direction which is July
Therefore X= July
And the sequence continues
Similarly, the month Y will be the sixth month from October in the backward direction which is April
Therefore Y = April
Therefore X=July and Y=April
Hence Option (b) is the correct answer.
