Question: What was the compression ration when the engine was Wasp Jr. T1B2?
SQL: SELECT "Compression ratio" FROM "1-1123802-1" WHERE "Engine" = 'Wasp Jr. T1B2';

Question: What is the compression ration when the continuous power is hp (kW) at 2,200 RPM and the octane rating is 80/87?
SQL: SELECT "Compression ratio" FROM "1-1123802-1" WHERE "Power, continuous" = 'hp (kW) at 2,200 RPM' AND "Octane rating" = '80/87';

Question: What is the compression ratio when the continuous power is  hp (kW) at 2,200 RPM and the critical altitude is at sea level?
SQL: SELECT COUNT("Compression ratio") FROM "1-1123802-1" WHERE "Power, continuous" = 'hp (kW) at 2,200 RPM' AND "Critical altitude This is the highest altitude at which the engine can achieve its full continuous power rating. Above this altitude, power falls off with height as with a naturally aspirated engine . See Supercharger#Altitude effects for details." = 'sea level';

Question: When the engine is Wasp Jr. T1B2, what is the number needed for takeoff power?
SQL: SELECT COUNT("Power, takeoff") FROM "1-1123802-1" WHERE "Engine" = 'Wasp Jr. T1B2';

Question: When critical altitude is sea level, what is the compression ration for a supercharger gear ratio of 7:1?
SQL: SELECT "Compression ratio" FROM "1-1123802-1" WHERE "Critical altitude This is the highest altitude at which the engine can achieve its full continuous power rating. Above this altitude, power falls off with height as with a naturally aspirated engine . See Supercharger#Altitude effects for details." = 'sea level' AND "Supercharger gear ratio" = '7:1';
