Background Paragraph: In Windows 2000 and later the threads in the System Idle Process are also used to implement CPU power saving. The exact power saving scheme depends on the operating system version and on the hardware and firmware capabilities of the system in question. For instance, on x86 processors under Windows 2000, the idle thread will run a loop of halt instructions, which causes the CPU to turn off many internal components until an interrupt request arrives. Later versions of Windows implement more complex CPU power saving methods. On these systems the idle thread will call routines in the Hardware Abstraction Layer to reduce CPU clock speed or to implement other power-saving mechanisms.
Story: John spends most of his time on computers. While at work his work computer does not need modern
capabilities. So, he still uses Windows 2000 at his office computer. At home it's a complete different ball game. He plays so much computer games at home that he needs a better computer. In his home computer he
installed the latest version of Windows. Now, there is no lag in his system.
Question: In John's home computer the idle thread will run or will not run a loop of halt instructios?

Ex Output:
will not run.

Background Paragraph: Air pollution is harmful to human beings and other living things. About 22 million people die from air pollution each year. Breathing polluted air increases the risk of developing lung diseases such as asthma and lung cancer. Breathing bad air also increases the chances of dying from other diseases. Children are most likely to be affected by air pollution. That's because their lungs are still developing and growing. Children also take in more air for their size than adults do. Some air pollutants damage the environment as well as the health of living things. The type of damage depends on the pollutant. Air pollution can also harm the environment.
Story: Two sister cities were part of an air pollution study. While Prague had big air pollution problems, Belfast was eco-friendly and its inhabitants were healthy.
Question: Which city had fewer people with an increased chance of developing asthma?

Ex Output:
Belfast.

Background Paragraph: Any unused energy in food, whether it comes from carbohydrates, proteins, or lipids, is stored in the body as fat. An extra 3,500 Calories of energy results in the storage of almost half a kilogram (1 pound) of stored body fat. People who consistently consume more food energy then they need may become obese. Obesity occurs when the body mass index is 30.0 kg/m 2 or greater. Body mass index (BMI) is an estimate of the fat content of the body. It is calculated by dividing a person's weight (in kilograms) by the square of the person's height (in meters). Obesity increases the risk of health problems such as type 2 diabetes and hypertension.
Story: Two men go into the doctor's office for a checkup. Stepping on the scale, the doctor weighs each of them. Tom has an average and healthy weight. However, Joe has a weight that indicates he is obese.
Question: Will Joe's risk of hypertension increase or decrease if he gains weight?

Ex Output:
increase.
