[Q]: 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?
[A]: will not run.


[Q]: Background Paragraph: When humans dig up and use fossil fuels, we have an impact on the carbon cycle ( Figure below ). This carbon is not recycled until it is used by humans. The burning of fossil fuels releases more carbon dioxide into the atmosphere than is used by photosynthesis. So, there is more carbon dioxide entering the atmosphere than is coming out of it. Carbon dioxide is known as a greenhouse gas , since it lets in light energy but does not let heat escape, much like the panes of a greenhouse. The increase of greenhouse gasses in the atmosphere is contributing to a global rise in Earth’s temperature, known as global warming or global climate change. 
Story: India decided to use fossil fuels to produce their electricity, and Nepal decided to go renewable and use only hydro power to produce their electricity. 
Question: Which country contributed more to a global rise in Earth's temperature?
[A]: India.


[Q]: Background Paragraph: During late adulthood, the risk of developing diseases such as cardiovascular diseases and cancer continues to rise. Most people also have a decline in strength and stamina. Their senses may start failing, and their reflex time typically increases. Their immune system also doesn’t work as well as it used to. As a result, common diseases like the flu may become more serious and even lead to death. The majority of late adults develop arthritis, and as many as one in four develop Alzheimer’s disease. 
Story: Two brothers were born 20 years apart. Tom, the older brother, was 72, while Dan was 52 years-old. they got along pretty well. 
Question: Which brother had a smaller chance of developing cancer?
[A]:
Dan.
