that平行的问题

Emily Dickinson’s letters to Susan Huntington Dickinson were written over a period beginning a few years before Susan’s marriage to Emily’s brother and ending shortly before Emily’s death in 1886, outnumbering her letters to anyone else.

B. Dickinson were written over a period that begins a few years before Susan’s marriage to Emily’s brother and ended shortly before Emily’s death in 1886, outnumber

这个B选项Ron的课里面讲的是that begins/ended不平行所以错了，应该是that begins/that ended

但是在下面这个题里面

                    Among lower-paid workers, union members are less likely than nonunion members to be enrolled in lower-end insurance plans imposing stricter limits on medical services and requiring doctors to see more patients, and spend less time with each.

               
                                

• that impose stricter limits on medical services and require doctors to see more patients, spend 这个正确选项，require前面没有that啊，所以到底平行的话要不要加上that
