But as the percentage of reduction ie 20% is not huge, it can be even recovered in a longer duration than the original plan. Option D can be eliminated using the same logic as of option C. Please clarify where my thought process is wrong

Responding to a pm:

The plan is to finance the improvements by increasing the toll on 2 highway bridges. What casts doubt on the plan?
The plan will be in trouble if the increase does not lead to increased collection.

Option (C) says that commuters can 'postpone' the effects of the increase. So it may take a little longer to get in the increased collection but you probably will see the increase.

Option (D) says that commuters switch to another route when toll is increased. So the overall collection may be actually less than before. This certainly casts doubt on the plan.

Hence, answer is (D)

kartickdey let me try to help

Question asks to select the option that would cast the most doubt on the effectiveness of the authority’s plan to finance the proposed improvements by increasing bridge tolls. We just have to find what creates the doubt. Option C and D are the only two among the 5 that are closer to most weaken

(C) Between the time a proposed toll increase is announced and the time the increase is actually put into effect, many commuters buy more tokens than usual to postpone the effects of the increase.- It says many commuters bought in advance to postpone the increase, many means more than 1 may be 2 commuters have bought 1000 tokens or 10000 tokens, or 100 have bought 10000 tokens, so what the duration is taken of 5 years, who knows this 10000 tokens may exhaust in one month only, after that those who bought they have to pay right. so this can't create much doubt.

(D) When tolls were last increased on the two bridges in question, almost 20 percent of the regular commuter traffic switched to a slightly longer alternative route that has since been improved.- It says 20% of regular commuter, that is still not known, how many regular commuters are there, if commuters are 100, 20 switched, if they are 100000 20% is 20000, this can be huge right. Also, this option shows the trend about the same situation, that something happened in past when similar type of situation happened, so there is possibility that if the toll will be increased, % of regular commuter may shift, this create the doubt effectivetly than C. Also the problem with C is about the commuters, we dont know whether those commuters are using those two bridges or not, but in D it specifically mentioned about the two bridges which is mentioned in the argument.

Hope this helps
