In a logistics warehouse, an automated sensor triggers an alarm if the internal temperature $T$ of a cold-storage unit satisfies the condition $T < 2$ or $T > 8$ (measured in degrees Celsius). Which mathematical term describes the combined set of all temperature values that would trigger the alarm?

A health and safety officer at a manufacturing plant is setting up an automated system that flags noise levels $n$ (in decibels) as 'unsafe' if $n < 40$ or $n > 85$. Match the following mathematical components of this safety system with their correct descriptions.

In a professional quality assurance workflow, a manufacturing component is flagged for rejection if its thickness $t$ satisfies $t < 4.5$ mm or $t > 5.5$ mm. True or False: The mathematical term for the combined set of all thickness values that would result in a rejection is the union of the two inequalities.

In a precision manufacturing facility, a quality control sensor is programmed to flag a component if its length $l$ satisfies the condition $l < 19.95$ mm or $l > 20.05$ mm. To determine the union of these two mathematical conditions, a technician must identify all length measurements that make ____ of the individual inequalities true.
