问题    In the past 12 months, Nigeria has suffered from a shrinking economy, a sliding currency, and a prolonged fuel shortage. Now, Africa’s largest economy is facing a food crisis as major tomato fields have been destroyed by an insect, leading to a nationwide shortage and escalating prices.
   The insect, Tutaabsoluta, has destroyed 80% of farms in Kaduna, Nigeria’s largest tomato-producing state, leading the government there to declare a state of【C1】______. The insect, also known as the tomato leaf miner, devastates crops by【C2】______on fruits and digging into and moving through stalks. It【C3】______incredibly quickly, breeding up to 12 generations per year if conditions are favorable. It is believed to have【C4】______in South America in the early 1900s, and later spread to Europe before crossing over to sub-Saharan Africa.
   In Nigeria, where tomatoes are a staple of local diets, the insect’s effects are devastating. Retail prices for a【C5】______of tomatoes at local markets have risen from $0. 50 to $2. 50. Farmers are reporting steep losses and a new $ 20 million tomato-paste factory has【C6】______production due to the shortages.
   Given the moth’s ability also to attack crops like pepper and potatoes, Audu Ogbeh, Nigeria’s minister of agriculture, has warned that the pest may "create serious problems for food【C7】______" in the country. Ogbeh says experts are investigating how to control the pest’s damage and prevent its spread, which has gone largely【C8】______until now.
   Despite being the continent’s second-largest producer of tomatoes, Nigeria is【C9】______on $ 1 billion worth of tomato-paste imports every year, as around 75% of the local harvest goes to waste thanks to a lack of proper storage facilities. A further【C10】______in local supplies is yet another unwelcome setback to the industry.
A)dependent I)originated
B)embarking J)reduction
C)emergency K)reproduces
D)feeding L)security
E)grazes M)terror
F)halted N)unchecked
G)handful O)untouched
H)multitude
【C5】
选项
答案G
解析 空格位于冠词a之后，介词of之前，由此判断应填入名词，且此名词可构成a______of的结构。该句含义为“当地市场上，______西红柿的零售价已经从0．5美元涨到2．5美元”，据此可排除multitude“许多，大量”，分别将reduction“减少，降低”，security“安全”和terror“恐惧，恐怖行为”代入句中，不是前后矛盾就是有悖常理，故答案为handful“少量，一把”，a handful of意为“一把，少数几个”。
