Final answer:
The statement about cell phone prohibition in SAP facilities unless they are government-issued is false. The necessity and proper clause does not limit but rather provides flexibility to national government powers. High-voltage wires are not insulated, and in photoconductive cells, a single electron expelled by a photon can create a current.
Step-by-step explanation:
The statement 'Cell phones are prohibited from being introduced into a SAP facility unless they are Government issued' is false. SAP usually refers to Special Access Program, which is a level of classification in the United States that imposes controls above and beyond those normally required for access to Confidential, Secret, or Top Secret information. The policies regarding the introduction of personal devices such as cell phones into such facilities are highly restrictive. Some facilities may not allow any personal electronic devices, while others may allow devices that meet certain security specifications or have been issued or approved by the Government. Therefore, the prohibition is not exclusive to cell phones not being government-issued; rather, it is about ensuring the security and integrity of the SAP.
Regarding the other statements: The high-voltage wires are indeed held aloft by insulating connectors, but they are typically not wrapped in an insulating material because the air acts as an insulator. Hence the statement is false. The necessary and proper clause actually grants flexibility to the powers of the national government rather than limiting them, so this statement is also false. Finally, a current in a photoconductive cell is created when a photon strikes and expels an electron, so it's true that even one electron can generate a current.
