input: Text: Booze You Can Use I love beer, but lately I've been wondering: Am I getting full value for my beer dollar? As I've stocked up on microbrews and fancy imports, I've told myself that their taste is deeper, richer, more complicated, more compelling--and therefore worth the 50 percent to 200 percent premium they command over cheap mass products or even mainstream Bud. And yet, I've started to wonder, is this just costly snobbery? If I didn't know what I was drinking, could I even tell whether it was something from Belgium, vs. something from Pabst? I'm afraid we'll never know the answer to that exact question, since I'm not brave enough to expose my own taste to a real test. But I'm brave enough to expose my friends'. This summer, while working at Microsoft, I put out a call for volunteers for a "science of beer" experiment. Testing candidates had to meet two criteria: 1) they had to like beer; and 2) they had to think they knew the difference between mass products and high-end microbrews. Twelve tasters were selected, mainly on the basis of essays detailing their background with beer. A few were selected because they had been bosses in the Microsoft department where I worked. All were software managers or developers ; all were male, but I repeat myself. Nearly half had grown up outside the United States or lived abroad for enough years to speak haughtily about American macrobrews. Most tasters came in talking big about the refinement of their palates. When they entered the laboratory (which mere moments before had been a Microsoft conference room), they discovered an experiment set up on the
  Question: What considerations (if any) did the author make on the amount of beer poured for each of the samples?
  
   (A) They only wanted the testers to have one sip of each
   (B) They poured differing amounts baked on the color to make them all appear the same color when you looked down into the glass
   (C) They provided one type of beer at a time to the tasters so that it would be at its fullest carbonation when they tasted it
   (D) They provided enough beer for several sips, but not so much that consuming all of it would be problematic
  Answer:
