I'm taking a test and have to guess the right answer to the question after the article. Article: Do you want to know something about the history of weather? Don't look at the sky. Don't look for old weather reports. Looking at tree rings is more important. Correct weather reports date back only one century, but some trees can provide an exact record of the weather even further back. It is natural that a tree would grow best in a climate with plenty of sunlight and rainfall. It is also expected that little sunlight and rainfall would limit the growth of a tree. The change from a favorable to an unfavorable climate can be determined by reading the pattern of rings in a tree trunk. To find the weather of ten years ago, count the rings of a tree trunk from the outside to the inside. If the tenth ring is far from the other rings, then it is certain that plenty of sunny and rainy weather occurred. If the rings are closed together, then the climate was bad for the tree. Studying tree rings is important not only for the history of weather, but also for the history of man. In a region of New Mexico you can find only sand---no trees and no people. However, many centuries ago a large population lived there. They left suddenly. Why? A scientist studied patterns of dead tree rings which had grown there. He decided that the people had to leave because they had cut down all the trees. Trees were necessary to make fires and buildings. So, after the people destroyed the trees, they had to move. In this instance studying tree rings uncovers an exciting fact about the history of man. Question: By studying the dead tree rings, the scientist discovered _ . Options: A: .where the people had left. B: what the people used to eat C: how the people left D: why the people had to leave

I'm taking a test and have to guess the right answer to the question after the article. Article: Roslyn Hing School on long Island recently started a pilot program using iPads in some classrooms.

The iPads are to be used in class and at hom during the school year to replace texbooks,allow students to correspond with teachers and tum in papers and homework tasks,and preserve a rocord of student work in digital files. "It allows us to extend the classes beyond _ "said larry Reiff,an English teacher at Roslyn who now posts all his course mateials online. But educators are still divided over whether practices to give every student a laptop have made a difference academically. "Thre is very little evidence that kids learn more,faster of better by using these machines,"said Larry Cuban,a retried professor of eduction at Staford University."IPads are excellent tools to attract kids,but then the fieshness wears off and you eget int hard-core problems of teaching and learning." But school leaders say the iPad is not just a cool new toy but rather a powerful and multifunctional tool with a number of applications,including thousands with educational uses. "If there isn't an application that does something I need ,there will be sooner or later,"said Mr.Reiff,who said he now used an application that includes all of Shakespare's plays. Question: The program of using iPads in class is _ . Options: A: widely accepted by most schools in the United States B: only an experimental one carried out in some schools C: a compulsory one carried out by the U.S government D: encouraged and organized by the iPad company

He has let me use his house to put on fund-raising events to raise money for youth at risk programs.

As a result, the boy' s high school career was continually interrupted. When he was a senior, he was asked to write a paper about what he wanted to be and do when he grew up." "That night he wrote a seven-page paper describing his goal of someday owning a horse ranch. He wrote about his dream in great detail and he even drew a diagram of a 200 acre ranch, showing the location of all the buildings, the stables and the track. Then he drew a detailed floor plan for a 4, 000-square-foot house that would sit on a 200-acre dream ranch." "He put a great deal of his heart into the project and the next day he handed it in to his teacher. Two days later he received his paper back.
