Answer: D: to warn them that tensions in town were escalating
Explanation:
In the book Roll of Thunder, Hear my Cry, Mr Jamieson, a white lawyer who is sympathetic to the black families in the south, comes to David Logan to warn him about tensions rising in town due to the boycott of the Wallace store which was run by the racist and violent Wallace brothers.
David Logan and his family had led a boycott of the Wallace General store such that black people stopped shopping there and began shopping at Vicksburg instead.
This started ruining the business of the Wallace store and this led to one of the brothers, Thomas Wallace, telling people he was going stop the purchasing from Vicksburg. Mr Jamieson upon hearing this, came to tell David (Papa) about the rising tension in the town.
