Even should we assume the grass that would be inside the circle is the same as that on the outside (a very reasonable assumption, to be sure), we must apply our knowledge of how droughts work. Droughts don't just affect isolated circular patches. The nature of that understanding rules out droughts as the culprit and thus B does nothing to strengthen the scientists' hypothesis.
@IvonneRosario Understood, thank you. I have been doing all these things and I really enjoy the new features on 7Sage as a whole. But I think this is one area that would still be great to bring back as it was so convenient.
I just switched to the new 7Sage yesterday. I noticed that I can no longer select the quick view feature for a question that would allow me to drag the image of the question to my desktop or to another tab. Up until now, I have been opening those and quickly dragging them to my wrong answer journal or to a word document for printing.
I would really appreciate if this feature was brought back and believe other students would benefit from this as well.
@sxphs No. C is not a necessary assumption as this argument is purely hypothetical.
For example, I could say that if I could travel back in time, I would be happy. Traveling back in time is not possible, yet that can be a true conditional statement as it is purely hypothetical.
Likewise, the conditional statement in this argument, indicating finding out the truth of the claim will allow the determination of whether psychic powers are possible, is a hypothetical statement which can remain true even if we do not have a way to trigger the sufficient condition.
