Which decision is correct?

You cancel the flight since the expected dangerous weather conditions along the route would demand too much of the passengers. Because of the expected turbulence you select a flight level below FL 250. Owing to these reports and taking into account the presence of heavy thunderstorms at planned FL 310 you select a higher flight level (FL 370). You show no further interest in these reports, since they do not concern the route to be flown.

96-The reason for the fact, that the atmospheric pressure of a polar front depression is normally lower in winter than in summer is that

050 4260 Climatology

the strong winds of the north Atlantic in winter are favourable for the development of lows. the low pressure activity of the sea east of Canada is higher in winter. converging air currents are of greater intensity in winter. the temperature contrasts between arctic and equatorial areas are much greater in winter.
