Allergies are on the rise in industrialized nations because improved hygiene has eliminated the microbes that, upon exposure, prompt infants' allergy-iihWrjng immune-system responses. Any ill effects of the rise in allergies, however, have been more than offset by the reduction in infant mortality caused by the elimination of pathogens. Further, current research suggests that future atergy-prevention therapies will compensate for the absence of beneficial microbes.
The statements above, 4 true, most strongly support which of the following?

• A. A family history of allergies does not elevate the risk that a child will develop allergies to food and other allergens.
• B. The rise in allergies has been accompanied by the development of effective treatments for the symptoms of those allergies.
• C. Increases In allergy seventy probably will not raise overall death rates unacceptably before therapies to prevent allergies become available.
• D. The prevalence of allergies will not continue to increase while substitutes for the beneficial microbes needed to prevent allergies are stiff being sought
• E. Advances in prenatal care for expectant mothers have contributed to the reduction in the infant mortality rate.

Sales promotions can involve selling a product at a relatively low price or selling the product with a free (or seemingly free) unit of the product, as in "buy one, get one free" campaigns. Research shows that immediately following month-long sales promotions, a postpromotion dip may occur, i.e., sales for the following calendar month may be less than sales for the calendar month preceding the sales promotion.
To increase sales, Storex, a department store, held month-long sales campaigns to promote four of its products. A sales promotion was considered successful if unit sales of the product were at least 10% higher in each of the 2 calendar months immediately following the promotion than In the month preceding it.
Experts have offered explanations for postpromotion dip:
* Explanation I: Many consumers stockpile the product at relatively low cost during the sales promotion.
* Explanation II: "Buy one, get one free" promotions cause some consumers to undervalue the product, making them less likely to buy it following the sales promotion.
* Explanation HI: Many consumers who missed a "buy one, get one free" opportunity may, as a result, develop so-called inaction inertia, i.e., become less likely to buy the product at either the regular or even at a discount price than if the sales promotion had not occurred.

Which one of the following is most strongly supported by the sales data, given the other Information provided?

• A. The April sales promotion for Product B was ineffective, unnecessary, or both.
• B. Consumers sought to stockpile Product B immediately following the April sales promotion.
• C. There had been a largely ineffective sales promotion of Product B in the preceding December.
• D. Sales of Product B would have increased in May and June even if there had been no sales promotion.
• E. No postpromotion dip in Product B sales resulted from a sales promotion held in the six-month period.
