A – Wrong
Option A unnecessarily makes a correlation between Standard of play in Britain declining and commitments outside the sport. Also, we cannot deduce that just because Young British competitors are affecting their own chances of wining, standard of play in Britain is declining.
B – Wrong
No information in the text suggests that British players are more interested in money.
C – Wrong
The text gives information about the friendliness of current players. However, we cannot deduce what the friendliness of past British players was.
D – Correct
The first line of the second paragraph is key to answering this question. It suggests that in the past, you could barely make a living by WINNING competitions. However, now you can make millions just by competing. Earning millions is more that what a person needs for a living.
E – Wrong
We have not information of outside commitments hindering British players’ performances.
