Part VII: Reading Comprehension

Question 156 - 157 refer to following paragraph:

ADELAIDE (2 February)–According to a recent report, ice cream sales in the region have fallen by nearly twenty percent this year. The decrease has surprised many, especially given the remarkably hot weather this summer. Local vendors pointed to an increase in the wholesale price of milk, which has caused their own prices to rise significantly.

To offset the decrease in sales, many ice cream stores are stocking alternative desserts that do not contain dairy. For example, Giordano's Dessert Shoppe in Wellington has begun selling fruit ices. According to analysts, because ice cream is a specialized market, traditional strategies such as increased advertising and customer discounts are not as effective as they are in other industries.

156. According to the article, why have ice cream sales decreased?

157. How are vendors responding to the trend?
