How come airline pilots can answer this question:

29. (Refer to appendix 2, figures 237, 238A, 239C, 231, 254 and 281B.) Given the following conditions, what are the takeoff V speeds?
Weight: 170,000 lb.
Flaps: 10°
Temperature (OAT): 25° C
Field pressure altitude: 427 ft.
Runway slope: 0%
Wind (KTS) Headwind: 8 KTS
Runway Condition: Wet Runway
For VR more than or equal to .1 VR, round up VR to the next value (example: 140 +.1 =141)

A. V1 134 kts., VR 140 kts., V2 145 kts.
B. V1 140 kts., VR 140 kts., V2 145 kts.
C. V1 138 kts., VR 141 kts., V2 145 kts.
