Correct. Sky 700 feet overcast, visibility 1-1/2SM, rain. [Time, wind direction and speed, visibility in SM, clouds, Temperature/ dew point, altimeter in inches of mercury. It is almost always the same format. Just go through and find the two wrong answers.]
Wrong. Sky 7000 feet overcast, visibility 1-1/2SM, heavy rain. [This can quickly be eliminated because it is always two zeros after the end for the altitude of the base of the clouds. It would be 700, not three zeros to make 7000.]
Wrong. Sky 700 feet overcast, visibility 11, occasionally 2SM, with rain. [Clever. Really clever. Looking at the other material, like LAX above which shows 6SM, that should have clued you in that the value for that place should be a number in statute miles.
