In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Q: Passage: Around noon, General Henry Abbot arrived at President Street with a battalion of 99 to 114 engineers. As the group advanced toward the armory of the 6th Regiment where they were to be quartered, they were met by a crowd of 500. Jeers from the crowd turned to missiles until one soldier, Private Corcoran, was struck in the head and wounded. Abbot gave orders that his men were to halt and fix bayonets, at which point the crowd scattered.Throughout the day and the previous, as many as 500 new special police were sworn in, doubling the size of the police force. Each was provided with a star, a revolver and espantoon. The recently arrived regulars brought the garrison of federal troops in the city to between 700 and 800. The vessels Powhatan and Swatara had also been ordered to the city, along with their 500 marines.News reports recalled court held that day in the southern district, where 195 charges of riot and 17 charges of drunkenness were resolved.

He was directed to move his men to Pittsburgh, where riots were ongoing.
