two identical spheres one hanging down with the help of an insulated wire. another is kept on an insulated block....
 
if both r provided with equal heat for the same time, whose temperature will b more??
Woods are lovely dark and deep
But i have promises to keep
And miles to go before i sleep
And miles to go before i sleep

here i think it is the surface area which one has to take into consideration.........the one hanging has more contact surface area with atmosphere so more heat is lost while for other as it is placed on an insulated block it has comparitively less surface area......

See i know they have not mentioned it is placed in atmosphere but they have even not mentioned vacum...and no other concept also seem to work...so it wud be most probably this only....
