Rodsky shared the spreadsheet on Facebook. Soon, she was receiving messages from strangers who had seen it, detailing the domestic indignities they faced. (l. 07-08). Consider the statements bellow about excerpts 1 and 2: I. In 1, the use of past perfect suggests that Rodsky doesn’t “shoulder the burden” anymore. II.
