Question

How has the US government used the Patriot Act to prevent terrorist attacks since September 11, 2001?

by using electronic surveillance of suspected terrorists
by offering rewards to terrorists who turn themselves in
by keeping information about suspected terrorists private
by opening its borders to better track suspected terrorists

Answer 1

by using electronic surveillance of suspected terrorists

The Patriot Act expanded federal surveillance and intelligence-gathering powers (e.g., roving wiretaps, broader access to electronic records and communications, and expanded FISA authority) to help detect and prevent terrorist activity. The other options do not describe primary features of the Patriot Act.
