c)the firm does not have sufficient time to cut its rate of output to zero.
d)a firm does not have sufficient time to change the amounts of any of the resources it employs.

Answer 1

first you didnt specify "short run", but any way as i analized what your saying, if am right "short run" short of budjet, not capable to put up a business,or the supposed establishment cannot expand/put branches because of incapacity of finances.
your FIRST basic-barriers to entry prevent new firm from entering the industry-my answer to this if the firms are basically lack of the above mentioned, definitely the rates will go down to zero.FOURTH-firm doesnt have sufficient time to change the amounts of any of the resources it employs(this i do not understand what you mean)but anyway as i analized, the firms always have sufficient time, as i said the firm has time table, time management, capital, good input, good profits/nets, and the firm always have options in case of shorts runs (finances)firm can apply a bank loan, there are always alternatives and solutions to the four characteristics you've mentioned. SHORT RUN in business/firm the causes are mismanagement, systems, unable to implies the rules, negligence in handling the finances,expenceses(accounting)auditing,always have an options(plan a and plan b) if the plan a goes wrong apply the plan b. hope in my own capacity and explanation i did clear-up the four characteristics of short run. you'll be the one to choose which is the right answer and applicable to your needs/
