Does effective advertising require a higher budget expense than ineffective advertising?Notice that the question stem uses the word "require."
"Require" is an indicator that something is necessary.
So, the question stem is asking whether a higher budget is necessary for effective advertising.
(1) Companies that allocate higher budgets to advertising tend to experience increased sales revenue.This statement indicates that a higher advertising budget can make advertising more effective.
At the same time, the question we need to answer isn't that of whether increasing the budget can make advertising more effective. The question is whether a higher budget is necessary for advertising to be effective at all.
So, what we need to notice here is that something helpful may not be necessary. For example, while increasing the budget may make advertising more effective, it could be that advertising could be made effective in alternative ways, without a higher budget. For instance, it could that low budget but very creative advertising is very effective.
So, this statement is not sufficient for confirming whether effective advertising requires a higher budget expense than ineffective advertising.
Insufficient.
(2) Effective advertising can drive higher consumer demand.This choice presents a result of effective advertising, "high consumer demand."'
However, we are seeking to determine what is necessary for effective advertising. So, this choice does not help with answering the question at all.
Insufficient.
Statements (1) and (2) combined.Since neither choice clearly indicates what size budget is necessary for effective advertising, the choices combined are not sufficient to answer the question.
Insuffcient.
