Answer 1

1。C but to do(not...but)
2。D 把are改成is（因为a number of表示大量的，修饰可数名词复数时，后面谓语用复数，the number of强调的是number这个单数）
3。B as John's(用名词性的物主代词，表示 John's company，比较级计较的对象要一致)
4。D asked his opinion(Mr. Boyd是被问问题，而不是他问，所以用V-ed形式表示被动)

Answer 2

1.[C] and to 把and 改成but

2. [D] are increasing 把are改为is

3. [B] as John把john改为 john‘s

4.[D] asking改为asked 后面是保留的直接宾语
