### Question #170

An argument claims that a new marketing campaign will double online sales because the campaign targeting young adults has been highly successful. Which of the following is an unstated necessary assumption?

* **Option A:** [A] Young adults represent the majority of the current online customer base.
* **Option B:** [B] Sourcing online sales campaigns from traditional channels will not decrease.

### Dynamic Answer Explanation

If we negate option A ('Young adults do NOT represent the majority of the current online customer base'), then doubling sales inside a tiny portion of customers will not double total online sales. The conclusion crashes completely, proving Option A is the necessary assumption.
