text_A: According to Fawkes, 20 barrels of gunpowder were brought in at first, followed by 16 more on 20 July. The supply of gunpowder was theoretically controlled by the government, but it was easily obtained from criminal sources. On 28 July, the ever-present threat of the plague again delayed the opening of Parliament, this time until Tuesday 5 November. Fawkes left the country for a short time. The King, meanwhile, spent much of the summer away from the city, hunting. He stayed wherever was convenient, including on occasion at the houses of prominent Catholics. Garnet, convinced that the threat of an uprising had receded, travelled the country on a pilgrimage.
text_B: Were the people Fawkes bought the gunpowder from likely to have been in prison before?
YES.
