What sparked a riot in new york city in 1863? food shortages and a rise in starvation a draft that was unfair to the lower classes a drop in employment in weapons factories the suspension of the writ of habeas corpus?

The correct answer is: "a draft that was unfair to the lower classes"

The riots that took place in New York City in 1863 are also known as the Draft Week. They were caused due to the opposition of the white working-classes to the enactment, by the US Congress, of a new draft to select men to participate in the ongoing Civil War. They considered such draft to be unfair as most soldiers were chosen from the lower classes".
