I used to have a teacher who said this as well. The best way to understand would be to show examples of how to specify such terms as “stuff” and “things”. For instance: “The birds have lots of stuff.” That was not clear because the reader does not know what the “stuff” is. Instead, the text could be changed to: “The birds have lots of feathers.” Now the reader knows what the stuff is because it has been replaced with a more specific word. If you go over multiple examples in your head, it will become easier to comprehend and you will get used to doing it.
I believe the answer is B. Nguyen explains how buses reduce traffic by lowering the number of cars on the road.
The passage says “Clearly, buses reduce traffic rather than cause it”. Answer B is the only answer that mentions traffic in a logical way.
I hope this helps!
The angels, not half so happy In Heaven,
Went envying her and me-
Yesl-that was the reason (as all men know,
In this kingdom by the sea)
That the wind came out of the cloud by night,
Chilling and killing my Annabel Lee
For the moon never beams, without bringing me dreams
Of the beautiful Annabel Lee;
And the stars never rise, but | feel the bright eyes
Of the beautiful Annabel Lee;
And so, all the night-tide, lle down by the side
Of my darling-my darling-my life and my bride,
In her sepulchre there by the sea-
In her tomb by the sounding sea.
