this kind of paper_______very soft A feel B feels

this kind of paper 中的kind为单位名词.凡是短语中带单位名词的,如a piece of ,a box of,a glass of 等,谓语动词应与单位名词保持一致.
如：1.These glasses of water are hot.
2.These box of apples tastes delicious.
例1中的water虽为不可数名词,但其单位名词glasses是复数,所以,动词be就应该为are ,而不是is；例2中的apples尽管是可数名词的复数,但其单位名词box是单数,所以,联系动词taste应相应的变为第三人称单数形式tastes,即在动词后面加-s.这就是语法书上所讲的“主谓一致”情况.
根据以上所述,This kind of paper ______ very soft.的答案就很明显了.B才是正确的选项.
