Honestly I didn't find this question worthy of 700 level, Please review the questions properly before posting under any specific level

I do not believe that C) is a necessary assumption.

Nowhere in the passage has it been stated that Don's plan requires schools' students to buy products from them.

If C were negated, there are still several possibilities that would lead to the plan's success: what if the teachers themselves shop a lot more, what if the school itself purchases more from Don's.

Could someone explain to me why it is necessary that 'teachers urge students' to buy from Don's?

Don's, a chain of supermarkets, has entered into an agreement in which Rose Computers will sell Don’s an unlimited number of its least expensive PC’s at one-fourth the regular wholesale price. In return, Don’s has agreed to purchase all of its scanners and other electronic information-processing equipment from Rose or from Omicron, Rose Computers’ parent company, for the next ten years. Don’s will offer a Rose PC free to any school that turns in Don’s register receipts totaling $100,000 within the next six months. The vice-president in charge of advertising for Don’s expects that the computer giveaway will obviate the need for a massive new advertising campaign for the next six months and that Don’s can make up the expenditures for the PC’s by writing them off its income taxes as charitable donations.

The plans formulated by Don’s assume each of the following EXCEPT:


(A) The prices that Rose or Omicron charges Don’s for information-processing equipment over the next ten years will be lower than those charged by other companies.
The prices that rose charge would be the same as they charge the other companies, because in batter they have given their other pC at 1/4th of the price. Had they not given it has 1/4th price, then to attract a deal with Don's they would have charged them less for information - processing equipment.

(B) The tax laws will not be changed to exclude or lessen the value of charitable donations as tax write-offs.
They have assumed it as they are going to write it in their charitable donation.

(C) Schools will be sufficiently attracted by Don’s computer giveaway offer that teachers will urge students to shop at Don’s.
Assumed in the deal.

(D) Rose will be able to supply Don’s with a sufficient number of PC’s to meet the demand generated by schools that collect Don’s receipts totaling $100,000.
Assumed.

(E) The effect of the computer giveaway offer on Don’s business will be comparable to that of a major advertising campaign.
Assumed

(A) The prices that Rose or Omicron charges Don’s for information-processing equipment over the next ten years will be lower than those charged by other companies.
THIS isn't explicitly stated in the argument just that they would supply and can it be compared with other companies is questiionable

(B) The tax laws will not be changed to exclude or lessen the value of charitable donations as tax write-offs.
Yes otherwise the the company will not be able to increase the profit margin

(C) Schools will be sufficiently attracted by Don’s computer giveaway offer that teachers will urge students to shop at Don’s.
Yes the campaign should generate enough intrest through school teachers enthusiasm otherwise the scucess rate can still decrease

(D) Rose will be able to supply Don’s with a sufficient number of PC’s to meet the demand generated by schools that collect Don’s receipts totaling $100,000.
Yes this is also prerequisite for the campaign , otherwise the image of the campaign will be damaged and scucess rate might dwindle

(E) The effect of the computer giveaway offer on Don’s business will be comparable to that of a major advertising campaign.
Yes even this is stated in the argument hence it has to be a valid point

Hence imo A

Hi Experts,

Can someone please explain why D is incorrect? The passage stated that there is an unlimited supply of PC by Rose

Yes you are correct. But what if Rose computers provides just half of the number of PCs to a school that totals a $100,000 in the span of first 6 months and the rest half of the number of PCs in the later six months?
In this case some schools, if not many, won't be able to get the total number of PCs required in one go. And that will be a bad advertising

ParamjitDasGMAT,

Please evaluate my reasoning for option B?
Option B when negated says that "Tax laws will be changed to exclude/lessen the value of ......."

So if tax laws will be changed, then what Don's plans to write off in charitable donations won't be possible. Hence, our conclusion is weakened.

Please share your two cents.
