Could you please explain Q.133 option A. All poets are singers. and some singers have negative relation with writers. So some singers (who has a 100% positive relation with poets) are not writer is true correct ? Also in option B, Chicken has a negative relation with beanstalks. So how can we conclude some chicken is not giant. As in the previous lessons, we saw if it would have been some giants are not chicken, then that can be true right ?

In option A, if all singers were negatively related to writers than the conclusion would have hold true. But not in this case. here just the singers and writers have a negative relation and poets are not necessarily involved in that.
