An extremely divisive issue, and gun control is discussed in all areas of the u.s. by people from.. B: an extremely divisive issue, gun control is C: extremely divisive as it is, gun control is
An extremely divisive issue是同位语,是对gun control的解释。 C项语法上没有错,但从逻辑上考虑,extremely divisive as it is是让步语气,在后句中就应该出现说它其实不那么divisive的意思,但后面的意思并不与前面形成转折,因此从句意是来讲应用B。
