A. read the passage and then choose the best answer:

Scientists around the world have been studying the warming of waters in the Pacific Ocean

known as EL Nino. The appearance of EL Nino is known to affect the weather around the

world. Scientists still do not completely understand it. Yet they now find they can use it to

tell about the future in different areas of the world.

One example is the work of two scientists at Columbia University in New York, Mark Cane

and Gordon Eshel. A scientist of Zimbabwe, Roger Buckland worked with them. They have

found that when EL Nino appears, Zimbabwe has little or no rain. This means corn crops in

Zimbabwe are poor. The last EL Nino was in 1991 to 1993. That was when southeastern

suffered a serious lack of rain.

The scientists wrote about their recent work in the publication "Nature". Their computer

program can tell when an EL Nino will develop up to a year before it does. They suggest

that this could provide an effective early warning system for southern Africa, and could

prevent many people from starving.
