The argument made in the paragraph is “To reduce this loss of young life…the driving test should require a much higher level of mastery”. We must find a statement which weakens this argument.
1 – Correct
The text says that the driving test should be made more difficult. However, it does not take into consideration that the young drivers may already be very skilled.
2 – Wrong
Having passengers in car during the accident is irrelevant to the argument made above.
3 – Wrong
The argument made is related to the difficulty of the test and not how much experience the drivers have.
Since only statement 1 is correct, A is the answer.
