input with options: Read the following article and answer the question. Article: Global warming is when the earth heats up,the temperature rises.It happens when greenhouse gases--carbon dioxide,water vapor,nitrous oxide ,and methane trap heat and light from the sun in the earth's atmosphere,which increases the temperature.This is like when heat is trapped in a car.On a very hot day,the car gets hotter when it is out in the parking lot.This is because the heat and light from the sun can get into the car,by going through the windows,but it can't get back out.Once the light is inside the car,it is trapped and the heat builds up,just like it does in the earth's atmosphere.This is what the greenhouse effect does to the earth.The heat and light can get through the atmosphere,but it can't get out.As a result,the temperature rises. Sometimes the temperature can change in a way that helps us.The greenhouse effect makes the earth appropriate for people to live on.Without _ ,the earth would be freezing,or on the other hand it would be burning hot.We would not get the sun's heat and light to make the night somewhat warm.During the day,especially during the summer,it would be burning because the sun would be up with no atmosphere to filter it,so people,plants,and animals would be exposed to all the light and heat. Although the greenhouse effect makes the earth able to have people living on it,if there gets to be too many gases,the earth can get unusually warmer,and many plants,animals,and people will die.They would die because there would be less food (plants like corn,wheat,and other vegetables and fruits).This would happen because the plants would not be able to take in the heat.This would cause us to have less food to eat,but it would also limit the food that animals have.Gradually,people,plants,and animals would all die of hunger. People are doing many things to try to stop global warming.One thing people are doing is carpooling.Carpooling is driving with someone to a place that you are both going to.This minimizes the amount of greenhouse gases put into the air by a car. Another thing that... Question: What is the effect of atmosphere? Answer:
OPTIONS:

- It makes the earth neither too hot nor too cold.
- It prevents all the light from the sun shining on the earth.
output: It makes the earth neither too hot nor too cold.

Q: Read the following article and answer the question. Article: Chokwe Selassie, aged 13, is working hard to help drivers avoid potholes . The eighth-grader was inspired to kick off his creation on a recent morning, when his mother was driving him to school. Their car was damaged as it went over a huge pothole in the middle of the street in their hometown of Jackson, Mississippi. He decided to do something about the pothole problem in his city. Chokwe developed the app with his friends Rodriguez Ratliff and Emmanuel Brooks. When the app detects a pothole, it is highlighted in red. And if you get close to the pothole, your phone will warn you with a beep. Drivers can also use the app to report any potholes and look for other routes they can take to avoid roads that have them. The app relies on current available information about the streets of Jackson, already stored in a database of the city's 311 call system. Through the call system, citizens dial 3-1-1 to report non-emergency problems which include potholes. Chokwe and his friends determined that focusing on the 10 busiest streets in Jackson would give them a large enough sample size to test the prototype. While developing the app, the boys took part in a Minority Male Makers Program sponsored by Verizon and held at Jackson State University. They learned 3D printing and design, and how to create apps. Through the program Chokwe and his friends received encouragement and guidance. Although the app isn't yet available for sale, Chokwe is already looking for ways to improve the app. He hopes to add more to it until it spreads all over the country. Question: Which can be Chokwe's future target? Answer:

OPTIONS:
- Encouraging more kids to create apps.
- Taking part in more learning programs.
- Making the app available for sale online.
- Making the app include streets nationwide.

A: Making the app include streets nationwide.

- the difference between standard English and non-standard English.
- the influence between standard English and non-standard English.
- the origin and development of standard English used nowadays.
- the difference between standard English and the London dialects. Now, answer this question: Read the following article and answer the question. Article: Standard English is that variety of English which is usually used in print,and which is normally taught in schools and to non-native speakers learning the language.It is also the variety which is normally spoken by educated people and used in news broadcasts and other similar situations.The difference between standard and non-standard,it should be noted,has nothing in principle to do with differences between formal and informal language:Standard English has informal as well as formal variants. Historically the standard variety of English is based on the London Dialect of English that developed after the Norman Conquest resulted in the removal of the Court from Winchester to London.This dialect became the one preferred by the educated,and it was developed and promoted as a model,or norm,for wider and wider parts of society.It was also the norm that was carried overseas.But not one unaffected by such export.Today,standard English is codified to the degree that the grammar and vocabulary of English are much the same everywhere in the world where English is used:difference among the local standards is really quite minor,so that the Singapore,South Africa,and Irish varieties are really very little different from one another so far as grammar and vocabulary are concerned.Indeed,standard English is so powerful that it puts a tremendous pressure on all local varieties,to the degree that many of the long-established dialects of England have lost much of their vigor and there is much pressure on them to converge towards the standard.This latter situation is not unique to English:it is also in other countries where processes of standardization are under way.But it sometimes creates problems for speakers who try to strike some kind of compromise between local norms and national,even super-national ones. Question: The main topic of the text is Answer:
A:
output: the origin and development of standard English used nowadays.
