System 2 thinking involves deliberate and conscious effort, and is necessary when confronted with complex tasks such as mathematical calculations or comparisons between different units of measurement. In this case, determining which temperature measurement is colder requires such effort.

Answer: D
 System 2 thinking is also necessary when recognizing faces and other visual stimuli, particularly when the information is ambiguous or unfamiliar. Therefore, recognizing a person in a photo would require System 2 thinking.

Answers A and C both require factual knowledge that could be retrieved quickly and easily from memory, so System 1 would be sufficient for these tasks.
