Read the passage given below. (8)
1. At a time when the use of fossil fuels to power vehicles is making environmentalists angry, an alternative
source of fuel — biodiesel — has emerged as a useful solution. Additionally, its use solves a disposal problem.The fuel is nothing but used vegetable oil which has been tested satisfactorily. It has made a vehicle called the Veggie Van (a motor home) run more than 16000 km across the United States. Also, ithas visited 20 major cities, causing absolutely no harm to the environment. Vegetable oils from variousrestaurantsin America were all that used along the entire journey. The novel experiment was started as acollege project by two students, Joshna and Kaia. It eventually ended in a massive public awareness
programme.
2. The idea of using vegetable oil as fuel for a diesel engine first occurred to them when they visited a
traditional farm in picturesque Southern Germany where vehicles fuelled by vegetable oil were in use.
While studying agriculture and living on these farms, they noticed that farmers were always filling vehicle
tanks with a yellow liquid. “This fuel comes from the canola plants which grow on our farms and nearby
areas. We use it in place of diesel and it smells good”, farmers said. The process of converting vegetable oil
into biodiesel fuel is cheap and easy to carry out. Any vegetable oil, such as used cooking oil, methanol or
clear alcohol can be used as fuel.
3. The diesel engine which is being used can run on altered vegetable oil or biodiesel without any
modification. Not only does biodiesel require zero modifications to the engine, this fuel works either by
itself or blended with petroleum diesel. Biodiesel has since been recognised as an official alternative fuel in
the US. Its use by the bus and truck fleet has soared by more than 100%.

Answer:
hi friend
