PT54.S1.Q08 (P2) - drilling fluids, including the various mixtures

I am confused by question 8. I was down to C and E, ultimately chose E, but only due to pure luck.

I don't know why C is supported but E is not.

The potential support for C is in line 23, where it says "one problem in studying the effects of drilling waste discharges..." But it just says there is a problem in studying. It doesn't say that the study is done. Perhaps the study wasn't done due to the problem. Who knows? Another potential support is just the whole second and third paragraphs of Passage B. They tell us that WBM is less harmful than OBM to the environment. That potentially implies that a study was done?

The potential support for E is in line 32, where it says that Drilling mud is normally released during the drilling phase of a well's existence. We know that the mud is discharged, although we don't know if it is continuously discharged into the sea.

To me, C and E both have weak support. I don't know why C is more supported than E.
