1. Detroit temperature's < Boston's temperature < Minneapolis's temperature
2. Minneapolis's temperature < Detroit's temperature < Boston's temperature
3. Boston's temperature < Minneapolis's temperature < Detroit's temperature
4. Detroit's temperature < Minneapolis's temperature < Boston's temperature

Answer 1

2. Minneapolis's temp<Detroit's temp<Boston's temp.

Answer 2

We will take one given at a time, the common place is "Detroit", so we will take it as a reference.

1- Detroit is colder than Boston, this means that:
Temperature in Detroit < Temperature in Boston .........> I

2- Detroit is warmer that Minneapolis, this means that:
Temperature is Minneapolis < Temperature in Detroit .........> II

From I and II, we can conclude that:
Minneapolis has the lowest temperature, followed by Detroit and then Boston.

Comparing this to the choices, we will find that the correct choice is:
2. Minneapolis's temperature < Detroit's temperature < Boston's temperature
