Well, I think an older generation may be able to learn new things that have never been seen before. Like the 1950's generation would not know much about technology and the more recent generation does. This is because they grew up in a different time than the newer generation. Different generations can understand each other by communicating (not just over text messages) and really talking to each other. If one does not understand another, please be kind and explain to the other what you mean.
it's C cause in the meaning of premise, it says a statement assumed to be true. that sentence about pretzel is assuming that pretzels are better than chips
