Field refrigeration units used to store perishable medical supplies rely on thermal sensors to regulate interior temperatures. Whenever the internal chamber temperature exceeds 4°C, an auxiliary cooling fan immediately activates to assist in lowering the heat. During a midday inspection at a desert outpost, a technician noticed that the auxiliary fan was actively running while the primary cooling compressor was operating at full capacity.
Based on the passage, which of the following conclusions is best supported?
- AThe medical supplies stored inside the refrigeration chamber were completely ruined by excessive heat.
- The temperature inside the refrigeration chamber was higher than 4°C at the time of the inspection.Answer
- CThe desert outpost experienced a severe electrical surge that damaged the primary cooling compressor.
- DThe primary cooling compressor shut down because the auxiliary cooling fan had activated.
Answer
The temperature inside the refrigeration chamber was higher than 4°C at the time of the inspection.
The passage establishes a direct conditional rule: the auxiliary cooling fan activates whenever the interior chamber temperature rises above 4°C. Because the technician observed the fan actively running during the inspection, it is a direct and necessary logical conclusion that the chamber's temperature was above 4°C.
