IMO D.

Issues covered in the sentence: Modifier and If / Whether.

"Reading reports and comparing statistical analyses" - Who does this - Authorities - So, this should precede authorities.
If - Used to state a condition.
Whether - To show 2 possibilities. Whether should not be accompanied by "or not". As it is implied.
In the given sentence, we have 2 possible outcomes - flight is approved or flight is not approved. We should use Whether.

Hi,

We have 2 possible outcomes here - flight approved or flight not approved.
Always for 2 possible outcomes, we use "whether".
To use if we need to have a condition.

Hope this helps!

Thanks

IMO E "whether or not"
Hi,

Whether or not is not the correct usage. It is always whether. For the same reason A is wrong. Only D is error free, as it uses "whether" only.

Here's my analysis.

Reading reports and comparing statistical analyses, authorities gather information about the weather along a flight route, but in some cases they find it particularly difficult to decide whether to approve a flight or not.


A. authorities gather information about the weather along a flight route, but in some cases they find it particularly difficult to decide whether to approve a flight or not - We can't use "whether .. or not" in a single sentence. It is a redundancy error. Rejected.

B. authorities gather information about the weather along a flight route, but in some cases they find it particularly difficult to decide if a flight should be approved - Here the context is missing which is there in the main sentence. Authorities fall in doubt with two available options such as "approve" or "disapprove". It would have been correct if it was mentioned as "they find it difficult to decide if a flight should be approved or not". Rejected.

C. information about the weather along a flight route is gathered by authorities, but in some cases they find it particularly difficult to decide whether to approve a flight - Here we have a modifier error. The preceding modifier "Reading reports and comparing statistical analyses" demands a noun which is being modified by it. So we can't use a passive voice with a wrong modifier usage. Rejected.

D. authorities gather information about the weather along a flight route, but in some cases they find it particularly difficult to decide whether to approve a flight - Here we don't have any redundancy error or modifier error. Seems correct.

E. authorities gather information about the weather along a flight route, but in some cases they find it particularly difficult to decide whether or not to approve a flight[/quote] - Redundancy error "whether .. or not". Rejected.

So, the answer is D.

Below is the quick analysis with the required rules:
1. Whether has "or not" implied in it
2. If is used for conditional clause
- to show uncertainty whether should be used

Check for verb-ing modifier(Reading reports and comparing statistical analyses) that is used before a comma(as in the case above)- such a modifier can modify either the following noun or the complete clause, depending upon the context of sentence
Here it is modifying the noun(authorities); correctness can be checked by using - Noun + Verb-ing modifier; if the said construction makes sense then the modifier is correctly used
i.e. Authorities read reports and compare statistical analyses(remove -ing)

If we apply all of the above rules then the only qualifying option is D
