Answer: the final stage. Now, what could be the question and solution-maybe?
Ques: The cell cycle, or cell-division cycle, is the series of events that take place in a cell leading to its division and duplication of its DNA (DNA replication) to produce two daughter cells. In bacteria, which lack a cell nucleus, the cell cycle is divided into the B, C, and D periods. The B period extends from the end of cell division to the beginning of DNA replication. DNA replication occurs during the C period. The D period refers to the stage between the end of DNA replication and the splitting of the bacterial cell into two daughter cells. In cells with a nucleus, as in eukaryotes, the cell cycle is also divided into three periods: interphase, the mitotic (M) phase, and cytokinesis. During interphase, the cell grows, accumulating nutrients needed for mitosis, preparing it for cell division and duplicating its DNA. During the mitotic phase, the chromosomes separate. During the final stage, cytokinesis, the chromosomes and cytoplasm separate into two new daughter cells. To ensure the proper division of the cell, there are control mechanisms known as cell cycle checkpoints.

Answer this question: when does cytokinesis occur in the cell cycle?
CoT: The important part for answering this question is: During the final stage, cytokinesis, the chromosomes and cytoplasm separate into two new daughter cells.

Seventeen people -- fourteen students and three staff members -- were fatally shot and seventeen others were wounded, making the shooting one of the deadliest school massacres. After being identified by witnesses and arrested by the Broward County Sheriff's Office shortly afterward, 19-year-old Nikolas Cruz confessed to being the perpetrator. He was charged with 17 counts of premeditated murder and 17 counts of attempted murder. Police and prosecutors have not yet offered a motive and are investigating "a pattern of disciplinary issues and unnerving behavior". The massacre surpassed the 1999 Columbine High School massacre as the deadliest high school shooting in American history.

Based on this passage, how old was the shooter in the florida massacre?
CoT: To answer this question, we should know that: After being identified by witnesses and arrested by the Broward County Sheriff's Office shortly afterward, 19-year-old Nikolas Cruz confessed to being the perpetrator.
