In the following questions six sentences are given. Further, these sentences may or may not form a contextually meaningful sequence, and one of these sentences is redundant to the context, which has to be eliminated. Rearrange the other sentences to make a contextually meaningful paragraph. The sentence (B), which has already been highlighted, would be the second sentence after rearrangement.

(A) Thirteen plumes of the gas were observed at the Raspadskya mine, the largest coal mine in Russia, in late January during a single pass of a satellite operated by GHGSat, a commercial emissions-monitoring firm.

(B) The finding is another indication of the scope of the problem of curbing emissions of methane, a potent planet-warming gas.

(C) By contrast, the highest rate measured at Aliso Canyon, a natural gas storage facility in Southern California that had a major leak for nearly four months in 2015 and 2016, was about 60 metric tons an hour.

(D) The total flow rate from all the plumes was estimated at about 87 metric tons (about 95 U.S. tons) an hour.

(E) A remote-sensing satellite has detected one of the largest releases of methane from a single industrial site, an underground coal mine in south-central Russia.

(F) Mr. Wight said it was not known how long the releases continued at this rate at the mine. But several previous satellite passes had detected emissions in the tens of tons an hour.

What is the correct rearrangement of the given sentences?
