But researchers say combining different farming methods may help. Since the world food crisis several years ago, researchers have directed more of their attention to small farms. Most farms in areas south of the Sahara Desert are only about one or two hectares. One of the goals is to increase production without necessarily clearing more land to grow additional crops. American researchers say that can happen with greater use of an agricultural system called perennation. It mixes food crops with trees and perennial plants - those that return year after year. Mr. Reganold, who is with Washington State University, says poor soil may have resulted from years of weathering that washed away many nutrients. He says some farmers may have done more harm than good. He estimates that up to two billion dollars worth of nitrogen, phosphorous and potassium is lost from African soil each year. The scientist says the word perennation defines three systems that are already used in Africa. The oldest of the three is called evergreen agriculture. This is where farmers plant trees with their crops. John Reganold says farmers in Africa have been doing this for sixty years, but it seems to be growing in popularity. The method is gaining widespread use in countries such as Niger, Burkina Faso, Malawi and Zambia. The trees are planted among maize, millet or sorghum crops. They not only add nitrogen to the soil through their roots, but also through their leaves when they fall off and break down. At other times of the year, the trees can protect plants from strong sunlight. Mr. Reganold was one of three researchers who wrote a report about perennation. It was published in the journal Nature.

Please answer this: Write a multi-choice question for the following article: Article: My wife and I have always been friendly with the clerks at the local store. I don't think many people appreciate what a difficult job these clerks have. They work for a little money and I often wonder how they make ends meet. One of the clerks, Charlie, was always wearing his glasses but he didn't one day. I asked him about it and he said they'd been out of order and that he couldn't afford a new pair. His family needed money. It was clear that he was having a difficult time. We wanted to help him, so we turned to our own eye doctor for help with a plan. We had his secretary contact him, asking him to come in for an eye exam for free. We told the doctor to let him order whatever glasses he wanted and that we would pay for them. Although Charlie questioned what was going on, the doctor just told him that someone had offered the money for his new glasses. When we went in to pay the bill, the doctor told us he was touched by our idea so that he _ the exam fee and only charged us for half the price of the glasses! It was so wonderful to see Charlie in his new glasses and he enjoyed telling all the regular customers how the gift came about. I'm sure that upon hearing his story, ideas of kindness may have come in the minds of many people.

Please answer this: Write a multi-choice question for the following article: Article: (RAMALLAH, West Bank) -- Israel freed 26 Palestinian prisoners early Wednesday, the second of four groups to be released as part of an agreement that started the current Israeli-Palestinian peace talks, which had broken down since 2008. In all, 104 prisoners are to be released in four rounds over the coming months. In the West Bank and Gaza , the mood was overexcited as hundreds of Palestinians welcomed the prisoners back home, after many had spent more than 20 years behind bars. Crowds of people rushed toward the 5 prisoners released to Gaza, raising them on their shoulders, waving Palestinian flags and dancing to music. Relatives held signs that read "we will never forget our heroes." More than 2,000 people welcomed the 21 prisoners released to the West Bank, who were greeted at a ceremony by Palestinian President Mahmoud Abbas in Ramallah. Hazem Shubair, thrown into prison in 1994 for the death of an Israeli according to the Israeli Prison Service, was over delighted upon his return to Gaza. "I am speechless," he said. "Thanks to God. God is greater than the aggressors (meaning Israel)". Abbas said a final peace agreement with Israel was possible on the release of the prisoners. "There will be no final agreement without the release of all the prisoners," he told the violent crowd. Israel's Supreme Court earlier refused an appeal that intended to cancel the prisoner release. An organization of bereaved families behind the appeal has said it fears the prisoners, all in connection to the deaths of Israelis, will return to violence once freed.
