Big Book - Test 9 - Section 4 - Question 7

Hello!
Please help me identify if my approach was correct for the below question.
For the below mentioned question, I copy pasted the ‘startling’ for the first blank and for the second blank I guessed the word ‘rejected’, since the finding was startling it will lead to some changes in the existing time-keeping methods. That led me to option A. Is my approach correct?


Thank You in advance for your help!
