India started taking measures to stop the growth rate quite early. India had the "National Family Planning Program" in 1952. It became the first country in the world to have a population policy. However, it failed to reach the final goal . Question: Over 65% of India's population is below the age of _ . Options: A: 25 B: 35 C: 45 D: 55

I'm taking a test and have to guess the right answer to the question after the article. Article: A 13-year-old American has made a cheap machine that can help blind people read. The blind can read by using _ - a system of small bumps that the blind touch to read the letters. The machine that makes these small bumps usually costs at least $2,000. It is called Braille writer. The American schoolboy, Shubham Banerjee, made a new Braille writer from a Lego tool that lets people create robots. Banerjee has called his new machine the Braigo - a combination of the words Braille and Lego. It costs just $ 350. It works by changing electronic text into Braille and then printing it using a computer or mobile machine. Banerjee designed his Braigo last year for a school science exhibition. Since then, he has caught the interest of Silicon Valley in the USA. The big technology company Intel spent money on Banerjee's machine last November, but they did not say how much money they put in. Banerjee also got $35, 000 from his father to help him start the project. His father works as a computer engineer at Intel. He spoke about why he gave so much money to his son, saying:"We as parents started to be interested more, thinking that he's on to something and this invention has to continue." Banerjee told the AP News: "My dream would probably be having most of the blind people...using my Braigo." Question: Banerjee's parents wanted him to continue to _ . Options: A: catch Intel's interest B: work on his invention C: be a computer engineer D: use the new Braille writer

I'm taking a test and have to guess the right answer to the question after the article. Article: Have you ever heard an echo of your voice? An echo is a reflected sound. Stand in a very large, empty hall with nothing on the walls. Then shout. The sounds you make will hit the walls and come back to you. The walls reflect the sounds. These reflected sounds are called "echoes". We can use reflected sound to make sound travel farther. Hold a watch about fifty centimeters from your ear. You cannot hear it. The sound of the watch travels a short way in all directions. It does not travel as far as your ear. You can make it travel to your ear by using a roll of cardboard . Make the roll of cardboard about fifty centimeters long. Put one end over your ear and hold the watch at the other. Now you can hear the watch because the sound has not gone in all directions. It is reflected down the roll to your ear. A megaphone works in the same way. It makes sound travel farther. It reflects the sound into a beam which can travel a long way. In the ship, the sailor uses the megaphone to make his voice travel. Without the megaphone, his voice cannot travel far. We use reflected sound in many ways. We use it to measure the depth of the sea, for example. Among the animals, bats and whales use reflected sound to tell them where they are and what things are near them. Question: . From the text we learn that _ . Options: A: reflected sound is useful only to blind people B: people haven't made use of reflected sound yet C: bats use reflected sound to fly and get food D: whales don't use reflected sound as they live in the sea
