Question

source: denby, charles. indignant heart: a black workers journal, wayne state university press, 1989.
the first time i went north was in 1924 ... the train stopped in covington, kentucky just as the sun was rising. someone said the bridge ahead was the mason-dixon line. we were north.
we didnt have to worry about sitting in back, we felt good ...

we agree that if there was one white man on the train with the seat beside him, wed sit there to see what he would do. we walked through the tray and feeling shaky. we thought any minute they would tell us to sit in the negro coach ... i continued to walk until i saw a seat by a white man. i was very uncomfortable for the first hour ... i relaxed some. he was reading a paper and when he finished half, he pushed it to me and asked if i wanted to read. he wanted to know where i was going and said, \detroit is a nice place.\ this was the most relaxing time i had.

can you give me a pull factor from this source?

Explanation:

A pull factor is a positive reason that draws people to a new location. From the source, the experience of greater social freedom and acceptance (not being forced into segregated seating, and a white passenger acting courteously, sharing a paper and being friendly) in the North, plus the positive mention of Detroit as a nice place, acts as a pull factor. It contrasts with the segregation and restriction the writer faced in the South, making the North an appealing destination.

Answer:

One pull factor from the source is the experience of greater social tolerance and freedom from rigid racial segregation in the North: the writer did not face forced segregation into a "Negro coach" as they expected, and encountered a white passenger who treated them with courtesy (sharing a newspaper and speaking positively about Detroit), creating a more comfortable and accepting environment compared to the South.
