ROBERT真是高手啊！

1.at any time in contrast,rather than is better than instead of ,and "increase in ..."is a fixed word.
2.the word"solution "has no reference ,so the correct answer is probably B or E,but "the prblem of perceptionis" the problem of computer,and the problem is not the "artificial version" but the problem of "artificial version",so the correct answer is the E.
3.I selected the wrong answer B too,but I think CDEis too complicated ,B IS WRONG MAYBE BECAUSE IT CAN NOT EXPRESS THE CONTRAST CLEARLY.
4.the position of the word "even can not be changed or the meaning will change too,and B so much as is used in negative sentence.so the correct answer is A.fficeffice" />
