Maintenance engineer: A temperature sensor in a refrigerated warehouse produces readings accurate to within 1°C whenever its battery voltage is above 3.5 volts. The sensor will be used to measure the warehouse temperature during a regulatory inspection tomorrow. Therefore, the reading taken during the inspection will be accurate to within 1°C. Indicate two different statements as follows: one statement identifies an assumption required by the maintenance engineer's argument, and the other identifies a possible fact that, if true, would provide significant logical support for the required assumption. Make only two selections, one in each column.

Maintenance engineer: A temperature sensor in a refrigerated warehouse : Two-part Analysis (TPA)

Assumption required	Possible fact
		The sensor's readings during several previous inspections were accurate to within 1°C.
		At every daily battery check during the past month, including today's check, the sensor's battery voltage was at least 3.9 volts.
		The sensor's battery voltage will be above 3.5 volts when the inspection reading is taken.
		The warehouse temperature usually changes by less than 1°C during any one-hour period.
		The sensor's battery is replaced whenever its voltage falls below 3.0 volts.
		The sensor can display temperatures throughout the range normally maintained in the warehouse.
