Joe's parents are farmers and they have a huge farm with cows, chickens, and ducks. Joe loves the farm and all the things he gets to play around and play on. One day, Joe's father told him not to get near a tractor that was sitting in the field. His father was worried that Joe would climb on it and hurt himself. Joe went out to the field and was feeding the horses and cows. When he was done, he saw the tractor his father told him not to get near. He knew that climbing on the tractor wouldn't hurt anything, so he did. He climbed on to the seat and sat there. Then, he pretended he was his father and pretended that he was driving the tractor. Joe's father saw him playing on the tractor and called for him. Joe heard his father calling for him and got off the tractor really fast. When he did that, he fell off and hurt his arm. Joe was in pain and his father came running to check on him and picked him up and sat him on a bench and asked him why he did that. Joe looked at his father and said, "I wanted to be like you." Joe's father gave him a hug and asked him if he wanted to ride with him on the tractor. Joe did and after he got a bandage on his arm, he and his father rode in the field on the tractor.

Washington The Iraqi government has agreed to let U.S. Rep. Tony Hall visit the country next week to assess a humanitarian crisis that has festered since the Gulf War of 1990, Hall's office said Monday. The Dayton Democrat, who has traveled to other crisis points including Sierra Leone and North Korea, will spend three days visiting hospitals and other facilities to seek understanding why aid has been ineffective in stemming malnourishment and other medical problems. Iraq has been under economic sanctions since the war ended, which some say have thwarted the country's ability to recover from the devastation of the bombing campaign. The Persian Gulf War destroyed much of the country's medical infrastructure, according to a report by the World Health Organization. In 1996 the WHO found that much of the population existed in a state of ''semi-starvation.'' Hall will be only the second member of Congress to travel in Iraq since the war, according to Hall's office. The last visitor was then-U.S. Rep. Bill Richardson of New Mexico, who went to help a pair of U.S. oilmen in diplomatic trouble. Hall flies to Amman, Jordan, on Friday, where he'll spend the night before driving to Iraq. Flights are not permitted into Iraq. Hall is to return to Washington on April 22. Story Filed By Cox Newspapers

Question: "How many U.S members of Congress visited Iraq before Hall?"

Response: "2"

A: no

Flowing water causes sediment to move. Flowing water can erode both rocks and soil. You have already learned that materials can dissolve in water. With enough time, even rocks can be dissolved by water. This process happens really slowly. It may take over a million years to dissolve a rock. It doesnt matter how big the rock is. With enough time, flowing water can dissolve it. Moving water also has the ability to move small pieces of rock and soil. How can water move a rock? Doesnt it need energy? Of course, water gets its energy because it is moving. Moving water has kinetic energy. Things that have more energy can do more work. When water stops moving it will have no energy. It will no longer be able to move the rock and soil. When this happens the rock and soil will settle to the bottom of the calm water. Scientists call this process deposition.

Question: "Why can water that is moving more do more work than water that is moving less?"

Response: "Water that moves more has more kinetic energy"

A:
yes
