Write a multi-choice question for the following article, with the given choices and answer: Article: Have you ever wondered? 1. Why do airplanes take longer to fly west than east? It can take five hours to go west-east from New York (NY) to London but seven hours to travel east-west from London to NY. The reason for the difference is an atmospheric phenomenon known as the jet stream. The jet stream is a very high altitude wind which always blows from the west to the east across the Atlantic.

In fact, some experts often tell parents to stay close to their kids by asking them about what's going on in their life. Some parents do this better than others, of course.

If you're tired of so many questions, tell your mom about your feelings the day before she asks. If you _ more information, conversations with your mom won't seem like she's just asking you too many questions! If you do this, I'm sure you can get on well with your mom.
