第二個選項要怎麼改呢？
89:Prehistoric villagers tended to work harder, suffer from more diseases, and eat the poorer diet than nomadic hunters did.
為何tended與eat的時態可以不一致？
113:In the United Stated, the first roads were paved in colonial times, first with logs, latest with cobblestones or brick, depending on the region.
第二個選項怎麼改呢？
128:Small to medium-sized marsh birds similar in body shape by cranes, rails are found throughout the world, except in the polar
regions.
第二個選項怎麼改呢？
137:The building knew as the Capitol is situated on Capitol Hill in Washington, D.C., and it houses the ldgislative branch of the United States government.
符號 ., 的後面，為何還要加and呢？

最後的as has space是什麼意思呢？
