Question: Read the following article and answer the question. Article: Nobody knows who invented the pencil or when it was invented. A Swiss described a pencil in a book in 1565. He said it was a piece of wood with lead inside it . Pencils weren't popular, and people continued to write with pens. In 1795,someone started making pencils from graphite and they became very popular. Today, people make pencils in the same way. They make the graphite into the shape of a stick, and then they put it inside a piece of wood. One pencil can make a line as long as 55 kilometers. When people first wrote with pens , they had to put the penpoint into ink after every few letters. Later someone invented a fountain pen and this kind of pen could hold ink inside. A fountain pen can write several pages before you have to fill it again. Two brothers, Ladislao and Georg Biro, invented the ballpoint pen that we use today. They left their country Hungary and started producing ballpoint pens in England in 1943 during World War II. Later, a French company called Bic bought the Biro's company. Someone calls ballpoint pens bics. Australians call them biros. Whatever we call them, we use them every day. Question: What do people use to make pencils today? Answer:
OPTIONS:
- Lead.
- Graphite.
- Sticks.
- Ink.

input with options: Read the following article and answer the question. Article: Can you speak to dolphins? Of course you can but you won't be able to understand them! We interviewed a biologist and asked her what research on dolphin communication has shown. This is what she told us. Just like dogs, cats and other mammals, dolphins communicate by using sound, vision , touch and taste. Each dolphin has its own signature whistle to identify itself and to call others. Dolphins don't have the ability to smell, but their hearing and eyesight are excellent. We also asked Jane if dolphins have got their own language. She told us that they have and that dolphins started talking to each other from birth. They make different sounds, including whistles, squeaks and click. Sometimes they even sound like a heavy metal band! We then asked Jane if any interesting experiments have been done. She told us that a very interesting experiment had been done with a mother dolphin and her two-year-old baby in an aquarium. They talked to each other over the telephone! The two dolphins were in separate tanks which were connected by a special under water system. Unfortunately the biologists couldn't understand what the dolphins were talking about because they haven't been able to decode dolphin language yet. However, it was very clear that the dolphins knew what they were talking about. Finally we asked Jane if there was hope that we would be able to understand dolphins in the near future. She told us that she and her team have been listening to dolphins for more than 17 years, using special equipment to record and analyze their language. Unfortunately they haven't been able to decode it yet, but who knows -- maybe one day we'll get a phone call from a dolphin. Question: The best title of the reading may most probably be _ . Answer:
OPTIONS:
- An Interesting Experiment
- Mother Dolphin and Baby
- Animal Talk
- Further Research
output: Animal Talk
