Step-by-step explanation:

Consider the provided statement.

It has been proved that the new double-shaft clubs result in longer drives. So if our drives are longer, then you are using these clubs.

From the above statement we can concluded that new club users are the subset of longer drives.

If you use double shaft you will definitely drive longer but if you drive longer  it is not necessary that you used a double shaft. It may be other factors.

Therefore, It may possible that you can drive longer without using the new clubs.

Therefore, the conclusion is invalid.
