Please do not give solution in image format thanku

Please help with these as they are part of 1 question and I am so confused. I really need help like never before and I will highly consider thumbs up but please help asap.  1- If fossil evidence of the most recent common ancestor of A and B (10 million years ago) was found on both sides of the river (that formed 20 million years ago), then the distribution of A and B is best explained by vicariance. ( choose true or false) 2- It is possible that species C will speciate.  ( choose true or false) 3- The distribution of the two species-C populations cannot be explained by two totally independent dispersal events by the common ancestor species of A and B.   ( choose true or false) 4- B must share a more recent common ancestor with C1 than it does with C2.  (choose true or false)
