Question $8$ of $31$

$8.$ Transnational criminal organizations attempt to gain access into the United States through cross$-$border tunnels and the illicit use of underground municipal infrastructure. U$.$S$.$ Customs and Border Protection $($CBP$)$ has a system to predict potential tunnel locations and to detect the presence of suspected tunnels and tunneling activities. If and only if the tunnel has already been detected can CBP$\text{'}$s system be used to project the trajectory of a tunnel.

From the information given above, it CANNOT be validly concluded that

A$)$ if a cross$-$border tunnel has been detected then CBP$\text{'}$s system can project its trajectory

B$)$ all cross$-$border tunnels that have been detected can have their trajectory projected by CBP$\text{'}$s system

C$)$ a cross$-$border tunnel has been detected if and only if its trajectory can be projected by CBP$\text{'}$s system

D$)$ if CBP$\text{'}$s system cannot project the trajectory of a cross$-$border tunnel, then the tunnel has not yet been detected

E$)$ if CBP$\text{'}$s system can project the trajectory of a cross$-$border tunnel, then the tunnel may not yet have been detected
