Read the passage and answer the questions that follow:
The Great Chicago Fire began on the city’s West Side, in the De Koven Street barn of Patrick and Catherine O’Leary, though it is not known what happened there. Vandals, milk thieves, a drunken neighbour, spontaneous combustion, even (though unlikely) the O’Learys’ legendary cow—any could have started that blaze, which roared out of control in minutes. Misdirected fire equipment arrived too late, and a steady wind from the southwest carried the flames and blazing debris from block to block.
Which of these is true according to the passage?
1
The storm carried the flames throughout the city
2
The reason for the fire remains unknown
3
The fire could be brought in control by fire equipments
4
Both 2 and 3
5
Both 1 and 2
