A.I. Explanation:

Option 1: "products online are more affordable for those who have lost their jobs."

Explanation: This option suggests that the affordability of products online is the reason for the growth of e-commerce. However, the text does not mention affordability as a factor; instead, it emphasizes convenience as the main reason consumers will continue to shop online.

Option 2: "the brick-and-mortar stores have yet opened due to the pandemic."

Explanation: This option implies that the closure of physical stores is the reason for the growth of e-commerce. While the pandemic has affected store operations, the text does not state that this is the primary reason for the anticipated growth in e-commerce. The focus is on consumer behavior rather than store availability.

Option 3: "consumers have learned how convenient it is to shop online."

Explanation: This option accurately reflects the main idea presented in the text. The woman states that consumers have learned the convenience of shopping online, which is a key reason she believes e-commerce will continue to grow. This aligns directly with her assertion that people are unlikely to return to physical stores soon.

Option 4: "there are more and more cellphones equipped with shopping apps."

Explanation: This option suggests that the increase in smartphones with shopping apps is driving e-commerce growth. However, the text does not mention mobile technology as a factor. The emphasis is on the convenience of online shopping rather than the tools available for shopping.
