input: OPTIONS:
- emphasize that taste and price are closely related to each other
- recommend that blind tasting be introduced in the quality control of colas
- show that taste preference is highly subjective
- argue that taste testing is an important marketing strategy Now, answer this question: Read the following article and answer the question. Article: Taste is such a subjective matter that we don't usually conduct preference tests for food. The most you can say about anyone's preference is that it's one person's opinion. But because the two big cola companies--Coca-Cola and Pepsi Cola are marketed so aggressively, we've wondered how big a role taste preference actually plays in brand loyalty. We set up a taste test that challenged people who identified themselves as either Coca-Cola or Pepsi fans: Find your brand in a blind tasting. We invited staff volunteers who had a strong liking for either Coca-Cola Classic or Pepsi, Diet Coke, or Diet Pepsi. These were people who thought they'd have no trouble telling their brand from the other brand. We eventually located 19 regular cola drinkers and 27 diet cola drinkers. Then we fed them four unidentified samples of cola one at a time, regular colas for the one group, diet versions for the other. We asked them to tell us whether each sample was Coke or Pepsi; then we analyzed the records statistically to compare the participants' choices with what mere guess-work could have accomplished. Getting all four samples right was a tough test, but not too tough, we thought, for people who believed they could recognize their brand. In the end, only 7 out of 19 regular cola drinkers correctly identified their brand of choice in all four trials. The diet-cola drinkers did a little worse----only 7 of 27 identified all four samples correctly. While both groups did better than chance would predict, nearly half the participants in each group made the wrong choice two or more times. Two people got all four samples wrong. Overall, half the participants did about as well on the last round of tasting as on the first, so tiredness, or taste _ , was not a factor. Our preference test results suggest that only a few Pepsi participants and Coke fans may really be able to tell their favorite brand by taste and price.

- changeable
- brave
- aggressive
- powerful Now, answer this question: Read the following article and answer the question. Article: Recently, while hiking in the foothills of South Carolina, I happened to notice a small, yet quickly flowing whitewater stream. While relaxing and enjoying the aloneness, I sensed a battle for favorable position between the highly-spirited water and the large rocks resting on the bed along the edges of the stream. At first; the rocks, stubborn, immovable and unbending, seemed to have their way with their adversary . However, the water, determined yet forgiving, seemed merely inconvenienced by the presence of the rocks, as it effortlessly changed its course, running towards its original destination. Soon it became clear that the rocks, although remaining strong and firm, were losing this battle as the water's total indifference began to slowly reform these obstacles into smooth and beautifully polished stones. You see, there seemed to be total lack of struggle associated with the water's journey. Struggle is like bondage forcing harmony and the water would have none of that. On the contrary,the water seemed perfectly content to move around the rocks when necessary, following some route God had originally intended. I paused for thought. Maybe people need to be more determined and less stubborn. Maybe human beings need to always be open to different points of view, not afraid to readjust their direction as life presents all of its new and unforeseen challenges. Question: The water won the battle mainly because it was _ . Answer:
