Which line from the passage contains the longest pause? a. well, son, i’ll tell you: b. and boards torn up, c. and places with no carpet on the floor— d. but all the time well, son, i’ll tell you: life for me ain’t been no crystal stair. it’s had tacks in it, and splinters, and boards torn up, and places with no carpet on the floor— bare. but all the time i’se been a-climbin’ on, and reachin’ landin’s, and turnin’ corners, and sometimes goin’ in the dark where there ain’t been no light.
