Direction: In each question below is given a statement followed by two conclusions numbered I and II. You have to assume everything in the statement to be true, then consider the two conclusions together and decide which of them logically follows beyond a reasonable doubt from the information given in the statement. Give answer
-
Statement:
The UN report, the latest in a series of four yearly reports reviewing the ozone layer since the Montreal Protocol (1987), has revealed that the hole in the ozone layer over Antartica is shrinking.
Statement:
I.We are now a point where the atmosphere can actually remove CFCs faster than they are being released into the atmosphere.
II. The level of destructive ozone-depleting CFCs in the atmosphere is declining.
-
- if only conclusion I follows
- if only conclusion II follows
- if either I or II follows
- if neither I nor II follows, and
- if both I and II follow
Correct Option: D
The statement merely says that hole in the ozone layer over Antartica is shrinking. The statement gives no clue about the comparison of rate of release of CFCs atmosphere and removal of CFCs from the atmosphere. Hence, I does not follow. The hole in ozone-depleting elements. But shrinkage of the hole does not imply II necessarily. Hence II does not follow.
