Problem:OPTIONS:
- the world's biggest animal
- lots of stories about whales
- laws to stop people killing whales
- the differences between dinosaurs and whales

Read the following article and answer the question. Article: Many people think the dinosaurs were the biggest animals that ever lived. They are wrong. The world's biggest animal is still living and it lives in the ocean . It is the blue whale . Blue whales can be as long as 30 meters and weigh as much as 1,000 kilos. The largest dinosaurs weighed only 500 kilos. The whale is not only the world's biggest animal; it is also one of the cleverest. We know that whales can talk with each other, but we do not know what they are saying. Maybe one day we will learn how to talk with whales, and then they will be able to tell us about themselves. Whales live in the ocean, but they don't _ eggs like fish do. They are mammals . They give birth to babies and have milk inside their own bodies to feed them. Humans are also mammals. Sadly, there are not many kinds of whales left. People have killed them for food and other things for a long time. Now there are laws to stop people killing most kinds of whales. So maybe there will be more of them in years to come. Question: The article mainly talks about _ Answer:

Read the following article and answer the question. Article: January 16, 2014 - We know the saying "The early bird gets the worm", but today you're going to learn about the interesting saying "The early fish gets the bird." An African tigerfish was seen jumping out of the air and catching a flying bird. The African tigerfish has bright red fins and very sharp teeth. There have been rumors this kind of fish preys on birds since the 1940s, but no one was able to catch _ . "The whole action of jumping and catching happens so quickly that after we saw it, it took all of us a moment to really understand what we had just seen," said Nico Smit from Environmental Sciences and Management at North-West University. Smit and his research team saw it at a lake in the Mapungubwe National Park in South Africa during summer. They found about 20 fish feeding on birds in the morning. Those birds may be out early to look for food, but we will never know for sure! Question: The tigherfish _ . Answer:

input with options: Read the following article and answer the question. Article: Have you ever wondered how and why a fall leaf changes color? We first have to understand what leaves are and what they do. Plants are the world's food factories. Plants take water from the ground and take CO2from the air. Plants use sunlight to turn water and CO2into glucose . Glucose is a kind of sugar. Using it as food, plants get energy and grow. Plants using sunlight to turn water and CO2into sugar is called photosynthesis . _ helps photosynthesis. It gives plants their green color. As summer ends and autumn comes, the days get shorter and shorter, and trees "know" to begin getting ready for winter. During winter, there is not enough light or water for photosynthesis. Trees rest during this time and live on the food they store during the summer. They begin to shut down their food -- making factories. As the green chlorophyII disappears from the leaves, we begin to see yellow and orange leaves. These colors have been in the leaves all the time. We just can't see them in the summer, because they are covered up by the green chlorophyII. The bright reds and purples we see in leaves are made mostly in autumn. In some trees, glucose is caught in the leaves after photosynthesis stops. Sunlight and the cool nights of autumn turn this glucose into a red color. The brown color of trees is made from waste left in the leaves. It is mixture of all these things. It makes the beautiful leaves during autumn. . Question: When they rest in winter, trees live on the food they store during the _ . Answer:
OPTIONS:
- summer
- autumn
- winter
- spring

summer
