List a reason why food may be wasted in a less economically developa2e3gk -*nyh led co+w jrzef91sg: untry (LEDC) and a more e +wr e9:sjzfg1conomically developed country (MEDC).
A. LEDC is Consumers buy more than they can eat before the food perishes,MEDC is There is not enough storage capacity for all the food so some of it goes to waste.
B. LEDC is There is limited refrigeration available to slow down the spoiling of food.,MEDC is Regulations set use-by dates that mean some food is thrown away when it is still edible.
C. LEDC is Poor roads mean food does not get to market to be sold on time.,MEDC is Consumers will buy whatever is available.
D. LEDC is Food is a large part of consumers’ budget so they only buy the best they can get.,MEDC is Standards for fruit and vegetables to be certain shapes mean ‘ugly’ food is thrown away.
参考答案: B
本题详细解析:
Option A is incorrect because many people in LEDCs cannot afford to buy more foo.wle fzp4 r52q8krop/ d than they can eat, and it is in LEDCs, not MEDCs, that some food is wasted because there is not enough good storage ce2/or rz5.p kql pw8f4apacity to protect food from spoiling or being eaten by other organisms.
Option B is correct. We use cold temperatures to prevent spoilage of food, but not enough is available in LEDCs. Strict regulations to protect people in MEDCs from consuming possibly spoiled food mean that use-by dates are set to consider worst possible cases. A lot of food is still perfectly edible after the use-by dates that regulations require, but many people throw it away after this date.
Option C is incorrect because consumers in MEDCs tend to be picky and buy what they feel like eating. This means that, inevitably, some food does not get bought and is thrown away. It is true that in LEDCs the roads are in general not as extensive and well-maintained. This leads to long travel times that means some fresh foods spoil on the way.
Option D is incorrect because in general, in LEDCs food is a large part of consumers’ budget. However, this means that they buy what they can afford and use it well, with as little waste as possible. It is true that in MEDCs fruit and vegetables that grow into a shape that does not meet standards set by the industry may be thrown away.
