question:  Why does the group want to buy a hydraulic press?
context: It is an uneasy privilege then, at least sometimes, to teach my old-fashioned brand of science to these children of a new age. "It has the purpose," I told her, "of teaching the members something about commerce and industry. They manufacture simple compositions like polishing waxes and sell them from door-to-door. Some groups have built up tidy little bank accounts which are available for later educational expenses." Mr. McCormack is going to put up fifty dollars to buy any raw materials wanted Back in the old Ridgeville, fifty-odd miles to the south, we had our home almost paid for, when the accident occurred. When Ridgeville moved to its present site, so, of course, did we, which meant starting mortgage payments all over again. This was to be our headquarters and factory for the summer—a roomy unused barn belonging to the parents of one of the group members, Tommy Miller. You're going to decide what to do, and if it's safe and legal and possible to do with the starting capital we have, I'll go along with it and help in any way I can. The usual products, of course, with these junior achievement efforts, are chemical specialties that can be made safely and that people will buy and use without misgivings—solvent to free up rusty bolts, cleaner to remove road tar, mechanic's hand soap—that sort of thing. "I'd like to make something by powder metallurgy techniques," said Pete. "You should be able to make ball bearings by molding, then densify them by electroplating." "And all we'd need is a hydraulic press," I told him, "which, on a guess, might cost ten thousand dollars. Healthy mice of the right strain," I explained to Tommy, "might be sold to laboratories. "Well, now," I admitted, "the market for red mice might be rather limited. There was a pause, then Tommy inquired, "How do you sell it?"
output:  They want to make ball bearings.
options:  They want to make cages for the mice.  They want to make ball bearings.  They want to make kites.  They want to make detergent.
