With the current settings the metal detector was able to find most metal objects regardless of type. With such a high sensitivity this would cause many follow up searches which increase the amount of time someone would need to spend to go through the security check. Using all the same items as before, more tests were conducted with lower sensitivity. 7. The following table shows the results of their testing, but it is not complete yet. Copy your answers from p. 2 (p. 258 in packet) questions 3, 4, 5, and 6, into the correspondingly numbered cells in the top row of the table.
