A Correct answer
Explanation

In India, climatic variations are wide between different parts of the country and, thus, the patterns of clothing or garments are also different. For example, the eastern, southern and western zone climates are similar and can be recognized as hot-humid tropics. Garments with a loose covering of the body are the special features of these zones and this type of garment is essential for air movement across the clothing worn. Northern zone people usually wear a long type of dress, such as the pyjama or salwar and long kurta due to the less humid climatic conditions.

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The first steam engine was invented by Thomas Newcomen in 1712 in England. However, Newcomen's engine was inefficient and could only be used near coalmines, where coal was abundant and cheap enough to run the engine. If steam engines were to have wider uses, they needed to be improved. James Watt studied the Newcomen's steam engine and introduced refined steam engine which was more efficient and more powerful in 1765.
