What Do You Think?

We have all had bad experiences with restaurants, stores, or hotels. Maybe you have gone to a restaurant that served terrible food. Perhaps you have gone to a store that had high prices or bad service. Or maybe you have booked a hotel and found out later that the room was nothing like the advertisement.

These days, we have a better chance of preventing these unpleasant surprises. We can do this by using apps. “App” is short for “application”. An app is a computer programme on a smartphone. You can use apps to do almost anything. Apps can help you play games, get directions, talk to friends, and so on.

If f you want to find information about a store or a hotel, you can use a review app. Review apps help us evaluate services and products before we hand over our money. The idea is very simple. After you go to a restaurant or stay in a hotel, you can post a review with one of your apps. You can say anything you want. If you like a hotel you stayed in, you can tell people that it was wonderful. If you think that the food in a certain restaurant was bad, then you tell people not to eat there. Other people can use their apps to read your reviews.

Plenty of people prefer not to use these review apps. Many of these people prefer to go out and decide for themselves whether or not a service is good. However, review apps are getting more and more popular every day. Some apps are for specific services. For example, Tripadvisor focuses on travel, and Goodreads focuses on books. There are also other, larger apps that provide information for just about every service that you can think of.

The word “it” in paragraph 3 refers to ________.

A. A restaurant

B. A hotel

C. A review

D. An idea

   It is hard to think of a world without gas or electricity. Both are commonly used for lighting and heating today. We now can instantly flick a lighter or strike a match to make a flame. But it was not long ago that there were no such things as matches or lighters. To make fire, it was necessary to strike a piece of iron on flint for sparks to ignite some tinder. If the tinder was damp, or the flint old, you had to borrow some fire from a neighbor.

   We do not know exactly when or how people first used fire. Perhaps, many ages ago, they found that sticks would bum if they were dropped into some hole where melted lava from a volcano lay boiling. They brought the lighted sticks back to make their fire in a cave. Or, they may have seen trees catch fire through being struck by lightning, and used the trees to start their own fires.

   Gradually people learned they could start a fire without traveling far to find flames. They rubbed two pieces of wood together. This method was used for thousands of years.

   When people became used to making fires with which to cook food and stay warm at night, they found that certain resins or gums from trees burnt longer and brighter. They melted resins and dipped branches in the liquid to make torches that lit their homes at night. Iron stands in which torches used to be fixed can still be seen in old buildings of Europe.

   There was no lighting in city streets until gas lamps, and then electric lamps were installed. Boys ran about London at night carrying torches of burning material. They were called torch boys, or link boys, and earned a living by guiding visitors to friends’ houses at night.

   For centuries homes were lit by candles until oil was found. Even then, oil lamps were no more effective than a cluster of candles. We read about the splendors and marvels of ancient palaces and castles, but we forget that they must have been gloomy and murky places at night.

What does “they” refer to?

A. people

B.ages

C. sticks

D. trees
