Input: Adult contemporary music
With the mixture of radio friendly AC tunes with some rock and pop fare also landing on the pop charts, mainstream songs won over many critics in the need to define AC, and appeared to change the tolerance and acceptance of AC music into mainstream day to day radio play. Part of the reason why more and more hot AC stations are forced to change is that less and less new music fits their bill; most new rock is too alternative for mainstream radio and most new pop is now influenced heavily by dance-pop and electronic dance music.

Who have hot AC format radio stations had to change the music they play?
Output: less and less new music fits their bill


Input: Article: Psychoactive drugs can impair the judgment of time. Stimulants can lead both humans and rats to overestimate time intervals, while depressants can have the opposite effect. The level of activity in the brain of neurotransmitters such as dopamine and norepinephrine may be the reason for this. Such chemicals will either excite or inhibit the firing of neurons in the brain, with a greater firing rate allowing the brain to register the occurrence of more events within a given interval (speed up time) and a decreased firing rate reducing the brain's capacity to distinguish events occurring within a given interval (slow down time).

Now answer this question: What causes humans to underestimate time intervals?

Output: depressants


Article: The essence of air defence is to detect hostile aircraft and destroy them. The critical issue is to hit a target moving in three-dimensional space; an attack must not only match these three coordinates, but must do so at the time the target is at that position. This means that projectiles either have to be guided to hit the target, or aimed at the predicted position of the target at the time the projectile reaches it, taking into account speed and direction of both the target and the projectile.

Question: Projectiles must either be guided to the target or aimed where?
Ans: at the predicted position of the target at the time the projectile reaches it


Here is a question about this article: In 1998, after the return of Steve Jobs, Apple consolidated its multiple consumer-level desktop models into the all-in-one iMac G3, which became a commercial success and revitalized the brand. Since their transition to Intel processors in 2006, the complete lineup is entirely based on said processors and associated systems. Its current lineup comprises three desktops (the all-in-one iMac, entry-level Mac mini, and the Mac Pro tower graphics workstation), and four laptops (the MacBook, MacBook Air, MacBook Pro, and MacBook Pro with Retina display). Its Xserve server was discontinued in 2011 in favor of the Mac Mini and Mac Pro.
What is the answer to this question: When was Mac's Xserve server discontinued?
****
So... 2011


The problem: Answer a question about this article:
Richmond's original street grid, laid out in 1737, included the area between what are now Broad, 17th, and 25th Streets and the James River. Modern Downtown Richmond is located slightly farther west, on the slopes of Shockoe Hill. Nearby neighborhoods include Shockoe Bottom, the historically significant and low-lying area between Shockoe Hill and Church Hill, and Monroe Ward, which contains the Jefferson Hotel. Richmond's East End includes neighborhoods like rapidly gentrifying Church Hill, home to St. John's Church, as well as poorer areas like Fulton, Union Hill, and Fairmont, and public housing projects like Mosby Court, Whitcomb Court, Fairfield Court, and Creighton Court closer to Interstate 64.
What neighborhood is located in between Church and Shockoe Hill?
****
The answer: Shockoe Bottom


The problem: Answer a question about this article:
Chopin also endowed popular dance forms with a greater range of melody and expression. Chopin's mazurkas, while originating in the traditional Polish dance (the mazurek), differed from the traditional variety in that they were written for the concert hall rather than the dance hall; "it was Chopin who put the mazurka on the European musical map." The series of seven polonaises published in his lifetime (another nine were published posthumously), beginning with the Op. 26 pair (published 1836), set a new standard for music in the form. His waltzes were also written specifically for the salon recital rather than the ballroom and are frequently at rather faster tempos than their dance-floor equivalents.
What did Chopin add to the modern dance of his era?
****
The answer:
greater range of melody and expression.
