Answer 1

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。

Answer 2

1.D =NO matter how much
2. how 后面只能跟形容词，
3. fallen是过去分词形式，而这句话用falling是现在分词形式作result in的伴随状语
4.whether后面接完整的句子

Answer 3

1，however要接修饰语，c没得
2，how要修饰副词之类的，what修饰名词
3。，result in决定的 ，in后面接ing 4，缺少宾语
