Answer:
Q:- 1. Read the passage given below and answer the questions that follow: (10)
1. At a time when the use of fossil fuels to power vehicles is making environments 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 satisfactory. It has made a vehicle called the Veggie Van
(a motor home) run more than 16000km across the United States. Also, it has visited 20 major cities, causing
absolutely no harm to the environment. Vegetable oils from various restaurants in America were all that used
along the entire journey. The novel experiment was started as a college 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 recognized as an official alternative fuel in the US. Its use by the bus
and truck fleet has soared by more than 100%.
On the basis of your reading answer any ten of the following questions:
(i) Where is this fuel obtained from?
(a) Diesel (b) Canola plant (c) Petrol (d) All of these
(ii) When did this novel idea occur to two students?
(a) When they were conducting experiments (b) When they visited a farm in Southern part of Germany
(c) When they conducted a massive public awareness programme (d) None of these
(iii)Biodiesel is considered an important alternative source of fuel because
(I) It power vehicles without causing harm to the environment (II) It comes from canola plants
(III) It smells good. (IV) It does not require any modification to the engine.
(a) I and II (b) II and IIII (c) III and IV (d) I and IV
(iv) The satisfactory result of using biodiesel to power vehicles can be seen from
I. The vegetable oils from various restaurants
II. A vehicle called ‘veggie van’ that covered 20 major US cities
III. The yellow liquid that comes from canola plant
IV. Veggie van causing no harm to the environment
(a) I and III (b) II and III (c) II and IV (d) III and IV
(v) Find a word in ‘para 3’ which means the same as ‘to make minor changes to’.
(a) Blended (b) modification (c) massive (d) alternatives
(vi) The fuel ‘biodiesel’ is
(a) Fossil fuel (b) animal oil (c) vegetable oil (d) petroleum
(vii) The project, started by two students Joshna and Kaia, ended in ……………………
(viii) Biodiesel has been recognized as an official alternative fuel in the US. (True/ False)
(ix) ___________ in ‘para 3’ means the same as substitute.
(x) The process of converting vegetable oil into biodiesel fuel is expensive to carry out. (True/ False).
