I realise that you can not change it now, and probably would not anyway on my advice
, however going by the qustions and answers you have posted here I do not think it is ever a good idea with these things to ask questions in the negative, like from memory question 9 you have posted.
I would naturally agree with this theory, however, this one is similar to the words used by many big companies for employee engagement surveys.
In practice it is like this. You have 50 odd questions. The agree option that appears on top is generally agreement with what the company is doing. If the question read -
There are substantial obstacles at work to doing my job well
Then the agree button gives an inverse answer to those questions appearing in the same section. It makes the survey flow better and reduces mistakes and confusion.
