I have the same thing happening to me! But instead of echo2155, for me it's JonHenderson55 who has been deleted my questions and answer FOR NOW REASON!!
The correct answer is - <span>Running takes discipline, and many people enjoy running.
This is faulty coordination because the first sentence is somewhat the opposite of the second one - usually, when something demands a lot of discipline and hard work, people are not going to enjoy doing that. This is why the coordination between these two sentences is wrong - it should say something like 'however, many people enjoy running,' instead of 'and.'
</span>
