NASA's methodical approach to the exploration of Mars has not yet answered the questions of whether biological life forms ever emerged on Mars and whether, presuming such life forms having left fossil traces to begin with, those traces can still exist in some moist recesses of the cold and arid planet.

2.Unlike the body’s inflammatory response to cuts and sprains, with widespread swelling and stiffness immobilizing the injured area until it heals, the body’s response to sunburn is more localized and resulting in a distinct line dividing affected and unaffected areas of the skin.
with widespread swelling and stiffness immobilizing the injured area until it heals, the body’s response to sunburn is more localized and resulting
where the injured area is immobilized with widespread swelling and stiffness until it has healed, sunburn generates a more localized response in the body, which results instead
with the injured area immobilized by means of widespread swelling and stiffness until healing, sunburn generates a more localized response in the body, one resulting
in which widespread swelling and stiffness immobilize the injured area until it has healed, the body’s more localized response to sunburn results
in which widespread swelling and stiffness immobilize the injured area until healing, instead, the body’s more localized response to sunburn results
答案应该就是3,4 第一题关于can,个人认为题目更强调的是those traces是否存在成为证据,而非是否"能"存在.因此弃用can 第二题当时做的时候由于时间比较紧看到the body’s response to sunburn对称就选了,现在想估计是with widespread swelling and stiffness immobilizing the injured area until it heals的问题,总觉得with后面不能这么说.请大牛指教.
