Question
Which letter among the following represents the mean position of the pendulum?
- A
- B
- O
- All the above
Hint:
It is the Position of the Bob when the freely suspended Pendulum is at rest.
The correct answer is: O
The Mean Position is the Position that is moderate between two other extreme positions. It is the Position of the Bob when the freely suspended Pendulum is at rest.
So Position O is correct

In the developing world, 1.1 billion people still do not have access to safe drinking water, 2.6 billion do not have access to adequate sanitation services, and waterborne diseases are responsible for more than 1.6 million deaths each year (mostly in children under five). Water is often too expensive or inaccessible to the poorest members of society in developing countries, while the wealthy have it piped into their homes. Furthermore, due to the infrastructure used to control water, entire seas are being lost, rivers are drying up, millions of people have been displaced to make room for reservoirs, groundwater aquifers are being pumped down, and water disputes have raised tensions from local to international levels. Fresh water is a scarce resource in many parts of the world, and it is expected to become even more so as the twenty-first century progresses.

Select topic sentence of below paragraph.
According to popular belief, while the dog is man's best friend, the coyote is his worst enemy. The coyote's bad reputation stems from his fondness for small animals; he hunts at night and is especially destructive to sheep, young pigs, and poultry. However, it is sometimes beneficial to coyotes. If valuable farm animals are protected, the coyote will frequently free the property of other animals, such as rabbits, which are destructive to the crops and certain trees. He is especially useful in keeping the rodent population under control. Where coyotes have been allowed to do their work without being harassed, ranchers and fruit growers have found them to be so valuable that they would not shoot them any more than they would shoot their dogs.
