If the same amount of heat is supplied to samples of 10.0 g each of aluminum, iron, and copper all at 15.0 ∘C , which sample would reach the highest temperature (see the table )?

I don't see a table but you can figure out the answer.

q = mass sample x specific heat sample x delta T
delta T = q/mass sample x specific heat. If q = constant and mass = constant we call them k and delta T = k/k*specific heat or
delta T = 1/specific heat. So you know that the metal with the lowest specific heat will give the largest deltaT. I think Al has the lowest specific heat of those listed.
