Answer 2

Answer:

I think the question you are looking for is as follows:-

A team of British scientists is developing “intelligent” clothes that will give disabled children   the power of “speech”. Children wearing waistcoats made of a unique electrotextile, linked to a   speech synthesizer, will be able to make themselves understood simply by tapping on the   touch-sensitive material.

The material is made up of normal cloth and an ingenious mesh of carbon-impregnated fibers   that can conduct electricity. When pressure is applied to the fabric, the pattern of signals that   passes through the conducting fibers is altered and a computer chip can work out where the   cloth has been touched. It then can trigger whatever electronic device is attached to it, which   could be no bigger than two boxes of matches.

"The smart bit is in how we weave the fabric and how we send signals through it – and we can   weave it into existing fabric designs so you cannot see it’s in there,” says one of the scientists.   Without being damaged, the material can be washed, wrapped around objects, or crushed. The scientist also claims it can be mass-produced cheaply.

Can these claims made in the article be tested through scientific investigation in the laboratory?  

The answer will thus be,

• It can be washed without being damaged as it is using carbon-impregnated fiber, hence it has to be waterproof.
• The materials can be wrapped around objects without being damaged as it is supposed to be touch-sensitive which works when we press them. Hence, this claim is true.
• Similarly, due to special fabric and coding, the material can not be damaged. So, the claim is correct.
• Finally, the last claim is that it would be produced cheaply. It is practically not possible. The making price will cost a fortune and labor making it impossible to produce it cheaply.
