1.因为however是副词,应该用来修饰形容词或副词,单独使用时解释为“无论怎么做”,如：It doesn't matter however you do it.无论你怎么做都无所谓.
2.what 修饰名词,how修饰形容词副词,这里what 修饰great pain.如果用how的话应该是how grat the pain
3.空格位置填的是result in 的宾语,和higher agriculture costs以及land shifted out of food production 并列,所以应和food stock一起形成名词短语.falling是现在分词,表示主动语态,意思是不断下降的粮食储备.fallen是过去分词,表示被动语态,粮食储备不是被下降,所以不能用
4.从句中的词组应该是：the scientist can make something of such material.由于make 后面缺少宾语,所以要用what.意思是：怀疑那个科学家能用这样的材料做出什么来.
