Question: Passage: Buy one, get one free -- Economist Alex Tabarrok has argued that the success of this promotion lies in the fact that the price actually takes into account the fact that two items are being sold. The price of ``one'' is somewhat nominal and is typically raised when used as part of a buy one get one free deal. Whilst the cost per item is proportionately cheaper than if bought on its own, it is not actually half price.
Question: is 2 for 1 same as half price

Answer: 0


Question: Passage: My Generation -- Another salient aspect of ``My Generation'' is Daltrey's delivery: an angry and frustrated stutter. Various stories exist as to the reason for this distinct delivery. One is that the song began as a slow talking blues number without the stutter (in the 1970s it was sometimes performed as such, but with the stutter, as ``My Generation Blues''), but after being inspired by John Lee Hooker's ``Stuttering Blues,'' Townshend reworked the song into its present form. Another reason is that it was suggested to Daltrey that he stutter to sound like a British mod on speed. It is also proposed, albeit less frequently, that the stutter was introduced to give the group a framework for implying an expletive in the lyrics: ``Why don't you all fff... fade away!'' However, producer Shel Talmy insisted it was simply ``one of those happy accidents'' that he thought they should keep. Roger Daltrey has also commented that he had not rehearsed the song prior to the recording, was nervous, and he was unable to hear his own voice through the monitors. The stutter came about as he tried to fit the lyrics to the music as best he could, and the band decided it worked well enough to keep. The BBC initially refused to play ``My Generation'' because it did not want to offend people who stutter, but it reversed its decision after the song became more popular.
Question: did the lead singer of the who have a stutter

Answer: 0


Question: Passage: Human hair color -- Hair color is the pigmentation of hair follicles due to two types of melanin: eumelanin and pheomelanin. Generally, if more eumelanin is present, the color of the hair is darker; if less eumelanin is present, the hair is lighter. Levels of melanin can vary over time causing a person's hair color to change, and it is possible to have hair follicles of more than one color on the same person. Particular hair colors are associated with ethnic groups. Gray or white hair is associated with age.
Question: is it possible for hair to change color
