b. False
Explicación
## Step 1The problem presents a statement about the operation of vacuums during the opening procedure of a tunnel. The statement is: "The vacuums do not need to be turned on during the opening procedure until the first car comes out of the tunnel."## Step 2The task is to determine whether this statement is true or false. The statement implies that the vacuums are not needed until the first car comes out of the tunnel.## Step 3However, in the context of tunnel operations, vacuums are typically used to ensure safety and smooth operation. They are used to remove any debris or obstacles that may pose a risk to the cars passing through the tunnel.## Step 4Therefore, the statement is false because vacuums are indeed needed during the opening procedure, not just when the first car comes out of the tunnel.
