Alice said Adobe was attacked this year, find the sum of digits of that year. (Alice - a) Bob said i would want to know the month as well, i'm curious. (Bob - b)

Hint : Modular arithmetics, monoalphabetic substituions. can anyone give any hints on which substitution this is ..I am thinking it to be affine but it is not working

my try : i searched that adobe was attacked in oct,2013 thus a=6,b=10 then i tried applying affine can anyone help me further..

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
