1) When intercepting the SFO VOR “054” radial, turn to a heading of “200”

2) Climb to “3000” feet

“I'll bet you've wondered at least a million times how to compute the range of San Francisco's VOR at your altitude of 3000 feet! Since it's a VHF signal, all you need to do is multiply your altitude above the ground by 1.5. Then take that product and find its square root. So at your present altitude, which I know you've nailed because of your outstanding scan pattern work, the approximate range of SFO VOR for you is 67 nautical miles! Now, you can relax your mind and think of something else!”

3) According to the Federal Aviation Regulations manual, what does the abbreviation “RAIL” stand for?

If your answer is “Runway Alignment Indicator Lights”,
