1.We consider the one-time pad with messages and key-streams both binary sequences. Suppose that the system is used erroneously, so that two messages have been encrypted using the same key. What information can an adversary that hears the two ciphertexts deduce about the plaintexts

no. when the asker posts the question they can make a question worth what ever they think is a fair price. although it must be within the limit of the points they currently own. 5 is the minimum number of points a question can be worth. if a question is complicated or has lots of parts to it, it is better to make it worth more because more people will be more willing to answer.

hope this !
