When two 500-ohm 1-watt resistors are connected in parallel, they can dissipate a maximum total power of:

Why

When two identical resistors are wired in parallel, each one shares the load equally, so the total power they can handle is simply the sum of their individual ratings. The full explanation — and one for every question — is in Pro.
