根据下列材料，请回答题This task is the same as Task 1. The 5 questions or unfinished statements are numbered 41 to 45. Scientists can determine someone' s favorite food from their body shape. They have discovered that the ar- rangement of taste buds(舌部味蕾．on the tongue varies for different body types. The scientist team examined1,000 British adults and divided them into three physiologically recognized body types—ectomorphs, endo- morphs and mesomorphs. They determined that a person' s body type indicated where they were likely to have the most taste buds on the sweet, bitter or salty areas of their tongue.
The study showed that ectomorphs, who make up one in three of the population, usually have a small deli- cate shape, have a sweet tooth but hate bitter foods. Mesomorphs, who make up 20 percent of the population, usually have a muscular shape and prefer salty or bitter foods but dislike sweet foods. Half the British population are endomorphy with soft, rounded bodies, and they like most foods. The findings showed that for two in three people food preference was a physiological rather than a psychological choice.
Body shape expert Simon Bradshaw, who takes charge of this team, said: "It appears that simply by loo- king at an individual' s body shape we can make sure about their preferences. " But Catherine Collins, of the British Dietetic Association said: "It is difficult to dictate whether our body shape dictates the food we like, or the food we like dictates body shape. " It stands to reason people who prefer most types of foods will be fatter and people who are the endomorph shape tend to find it more difficult to lose weight.
The whole passage is mainly about A．how to lose weight
B．a report on your body shape and favorite food
C．how body shape is determined by the arrangement of your taste buds
D．how body shape has something to do with your taste buds
