Do the same (as in Set C) for each of the following:

All logicians are deep thinkers and effective writers. To write effectively, one must be economical if one’s audience is general, and comprehensive if one’s audience is technical. No deep thinker has a technical audience if he has the ability to reach a general audience. Some logicians are comprehensive rather than economical. Therefore not all logicians have the ability to reach a general audience. (Lx: x is a logician; Dx: x is a deep thinker; Wx: x is an effective writer; Ex: x is economical;

Gx: x ’s audience is general; Cx: x is comprehensive; Tx: x ’s audience is technical;

Ax: x has the ability to reach a general audience)
