Answer: 10 seconds 
Explanation: 
m here means mean. 
Mean or more accurately arithmetic mean, is calculated by adding all the terms and then dividing by the number of terms. 
If there are 5 terms being 4, 5, 5, 6 and a fifth one which is x, and the mean is 6. The relevant expression is:
(4 + 5 + 5 + 6 + x) / 5 = 6
Solving it:
4 + 5 + 5 + 6 + x = 6 * 5 
20 + x = 30
x = 30 - 20
x = 10 seconds

Answer: 
E. After “robots”
Explanation: 
Answer E 
Correct . The underlined text is a modifying phrase that describes the word “robots.” By placing the phrase directly after the word it modifies, the writer can reduce ambiguity in the sentence. This choice makes it clear that the modifying phrase refers to robots, not people.
