To find out how many activities are taking place at a given time in a Gantt chart, ________
A) read across a single row
B) read down a single column
C) count the total number of bars
D) count the total number of actual progress bars
Answer: B
Explanation: A strength of a Gantt chart is that it allows users to read down a single column and get an instant assessment of how many activities are taking place at a given time, making reading down a single column the correct response. The more bars that the line goes through, the more activities that are taking place at that point in time. Reading across or counting bars do not provide simultaneous activity information so they are incorrect responses.
