a) Change "Lillian and Frank" to "Frank and John"
b) Change "reducing" to "increasing"
c) Change "people" to "machines"
d) Change "task" to "experiment"

Answer 1

To make the sentence true, we need to change the word 'reducing' to 'increasing'.

Step-by-step explanation:

To make the sentence true, we need to change the word 'reducing' to 'increasing'.

The original sentence states that Lillian and Frank Gilbreth tried to make workers more efficient by reducing the number of people required to perform a task. However, this goes against the goal mentioned in the sentence. If the goal is to make workers more efficient, then reducing the number of people required would not be the desired outcome. Instead, increasing the number of people required would align with the goal of making workers more efficient. Therefore, option b) Change 'reducing' to 'increasing' would make the sentence true.
