11. Read the following passage carefully and answer the questions given at the end of it :
Think of an electric car that can accelerate swiftly to cruising speed, laptop computers that can recharge in a couple of minutes rather than hours and a generation of super-miniature mobile phones. That’s the vision sketched by a pair of scientists in the United States, unveiling an invention that they say could lead to a smaller, lighter and more power-packed lithium battery than anything available today. Current batteries made of lithium iron phosphate (LiFePO4) are good at storing large amounts of electricity but stumble at releasing it. They are better at dispensing the power in a steady flow than at discharging it or gaining it in a sudden burst. As a result, electric cars perform best when travelling along the motorway at a constant speed rather than when they are accelerating, and their batteries take hours to recharge when they run down. Until now, the finger of blame has pointed at charged lithium atoms. These ions, along with electrons, move too sluggishly through the battery material before arriving at the terminal to deliver their charge — or so it was thought. But two materials experts at the Massachusetts Institute of Technology (MIT) say the problem lies not with the ions but rather at how the ions gain access to nano-scale tunnels that riddle the material and transport the electrons to their destination. Their solution was a lithium phosphate coating that, like a system of feeder roads, nudges the ions towards the tunnels. The ions then zip instantly down the tunnel entrance and to the terminal. A small cellphone battery can be recharged in just 10 seconds, thanks to the improved ion flow, they report in the British journal Nature. In theory, a large battery that would be used to power a plug-in hybrid electric car could be recharged in just five minutes, compared to up to six or eight hours at present. But this would only be possible if a beefed-up electricity supply were available. Unlike other battery materials, the tweaked LiFePO4 does not degrade as much when repeatedly charged and recharged. This opens the way to smaller and lighter batteries, which will not need such heft to deliver the same power. The invention, which was supported by US government funds, has already been licensed by two companies. Because the material involved is not new — the difference is the way it is made — "the work could make it into the marketplace within two to three years," it said. The invention is the latest claimed advance in the quest to replace conventional electro-chemical batteries, which are heavy, lack energy density and take time to recharge.

15. Given below are two passages. Read one of them to draw a flowchart.
(a) The process of making photocopies
Static electricity enables a photocopier to produce almost instant copies of documents. At the heart of the machine is a metal drum which is given a negative charge at the beginning of the copying cycle. The optical
system then projects an image of the document on the drum. The electric charge disappears where light strikes the metal surface, so only dark parts of the image remain charged. Positively charged particles of toner powder are then applied to the drum. The charged parts of the drum attract the dark powder, which is then transferred to a piece of paper. A heater seals the powder to the paper, and a warm copy of the document emerges from the photocopier
(b) The process of making bread Bread is eaten in most parts of the world, but not everyone knows how to bake it. I am going to show you the steps involved in baking bread. First, measure the correct amount of flour and warm water. Next, mix the flour and water together in a mixing bowl. Add yeast, salt and sugar. Next, knead the mixture until it feels almost dry. Leave the mixture for about an hour in a warm place. It will grow in size. After this, knead the mixture again. Make sure the mixture is not sticky when you touch it. Then leave the dough in a baking tin for about an hour to give it time to rise. Finally, the dough is put into a preheated oven for about forty minutes. It can be seen that making bread is not difficult as long as the correct procedure is followed. You will love the taste and smell of your freshly baked bread!
