This task is about reading the given passage and construct a question about the information present in the passage. Construct a question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) the answer is unique, (iv) its answer is a continous text span from the paragraph. Avoid creating questions that (i) can be answered correctly without actually understanding the paragraph and (ii) uses same words or phrases given in the passage 

Let me give you an example: "story": "Traditionally considered the last part of the Stone Age, the Neolithic followed the terminal Holocene Epipaleolithic period and commenced with the beginning of farming, which produced the "Neolithic Revolution". It ended when metal tools became widespread (in the Copper Age or Bronze Age; or, in some geographical regions, in the Iron Age). The Neolithic is a progression of behavioral and cultural characteristics and changes, including the use of wild and domestic crops and of domesticated animals. 

The beginning of the Neolithic culture is considered to be in the Levant (Jericho, modern-day West Bank) about 10,200 – 8,800 BC. It developed directly from the Epipaleolithic Natufian culture in the region, whose people pioneered the use of wild cereals, which then evolved into true farming. The Natufian period was between 12,000 and 10,200 BC, and the so-called "proto-Neolithic" is now included in the Pre-Pottery Neolithic (PPNA) between 10,200 and 8,800 BC. As the Natufians had become dependent on wild cereals in their diet, and a sedentary way of life had begun among them, the climatic changes associated with the Younger Dryas are thought to have forced people to develop farming."
The answer to this example can be: What did Neolithic follow?
Here is why: This question is based on the following sentence in the passage - the Neolithic followed the terminal Holocene Epipaleolithic period and this is answerable from the passage. So, it is a good question.

OK. solve this:
Local businessmen are increasingly facing competition from online retailers. Larry Pollock, owner of Camera Co/Op on South Congress, said he has been dealing with this kind of problem for years, even before the Internet. The struggle began with mail-order catalogues , which are similar to online retailers in that they have few employees to pay, no sales tax fees and no business venue to lease and manage. 

"Their overhead is lower, but they don't offer a service like we do," Pollock said. 

Pollock, however, said providing a valuable service to customers does not always guarantee continued sales. 

"We spend 30 minutes to an hour with somebody and they go home and buy it on line," he said. 

According to the state comptroller's office, online shopping is developing at a more rapid rate than traditional businesses. 

In spite of how fair or unfair online shopping may be to the local businessmen, consumers will continue to turn to the Internet for its variety and accessibility, said Mitch Wilson, an online shopper. "You have a larger selection and it's easier to compare prices." 

Wilson said he built his personal computer and paid a third of the price by shopping on line. 

"Before the Internet, I would have had to go and buy an assembled computer from somebody like Dell," he said. "Before I started shopping on line I could never find all the pieces I wanted. No single store had everything needed, so shopping on line saved me from having to buy from Dell." 

Janny Brazeal, a psychology freshman, said online shopping is too impersonal. 

"'d rather see it in person, touch it, know that I'm getting it," she said. 

Brazeal also said she would not give out her credit card number or other personal information on line no matter how safe the site claims it is.
Answer:
What is a valuable service?
