33) D

A – Wrong
We know 85% cycle less than once a week but we do not know what distance.

B – Wrong
We know an average person makes 14 trips a year. This equates to more than 1 per month. However, this is clearly wrong as we cannot say this for every UK resident.

C – Wrong
We do not have enough info to conclude this.

D – Correct
15% cycles at least once a week
8% cycles at least once a month. Minimum 12 trips
69% cycle less than once a year. Maximum 1 trip
Remaining = 100 – 15 – 69 – 8 = 8%
So the remaining 8% must travel between 1 and 11 times a year.
