The very last option is the correct answer.
The Karez Well System is an important ancient irrigation system. It is made up of a horizontal series of vertical dug wells that are linked to each other by underground water canals. This system provides water to drink for local people as well as to water their crops. The water was collected from the mountains which are miles away from the farmland. Thus, this system transfers water from mountains in form of groundwater to people which are miles away.
Hence, the Karez well system transported groundwater from a distance.

If you want to go back to the previous definition of a calorie, the amount of heat required to raise 1 gram of water by 1 degree C, you can derive that ~4.2 J/Calorie figure by unit conversions. You need to know that a Joule is measured experimentally as 4200 Joules to raise 1 kilogram of water 1 degree C.
Answer:
A) 50-52
explanation:
Assuming the body has been in a room temperature area, the victim has been dead for 50-52 hours. As a rule of thumb, dead bodies lose about 1.5 degrees Fahrenheit per hour. Average body temperature in Celcius is 37 so to find the amount of heat lost, 37 - 13.5 = 23.5. Converted to Fahrenheit, 23.5C = 74.3. Now to find the amount of hours passed by dividing the difference in average temperature and the bodies current temperature by the average heat lost per hour. 74.3 / 1.5 = 49.59... or 50 when rounded up. Therefore the victim has been dead for approximately 50 hours.
