exposures vs claim count for classical credibility

I am confused as to whether a question is asking for credibility for exposures or claim counts... can someone tell me when to use which?

I've attached a problem below... what is the giveaway in the problem that says you need to use exposures?

Because of part (iii) I would immediately start solving for n_c, the number of claims for credibility. Then later they are asking a comparison with the group size as the variable n. Group size comes from the number of people, or exposures. So convert n_c to n_e by dividing by the frequency mean (btw, just memorize the n_c formulas then convert if needed).

I can't say I've seen too many ambiguous problems; they usually specify exposures if they want exposures.
