Final answer:
Ping-pinging procedures may be preferred over calling a conference committee to reconcile differences between the Senate and House due to structural differences and flexibility in the legislative process.
Step-by-step explanation:
When reconciling differences between the Senate and House, using ping-pinging procedures may be preferred over calling a conference committee due to structural differences and the legislative process. Senators tend to view committee decisions as recommendations, while representatives in the House defer to committee decisions. Additionally, the Senate has more flexibility in its rules for debate and can allow members to slow down or stop legislation they dislike. Ping-pinging procedures involve communication between the chambers to reach a compromise on the bill without the need for a conference committee.
