Eight professors of a college, namely X, Y, Z, A, B, C, D, and E, are sitting around a square table in such a way that four of them sit at the four corners of the table while the other four sit in the middle of each of the four sides, all facing each other towards the center. C sits to the immediate right of A, who faces Z. E sits opposite to X, who sits to the immediate right of Y. B sits to the immediate left of Y and opposite to C. Who among the following faces Y?

Seven people, C, D, E, F, W, X and Y, are sitting around a circular table facing the centre. Only two people sit between C and D when counted from the left of D. X sits to the immediate right of D. Only three people sit between D and E. F sits to the immediate right of W. How many people sit between Y and F when counted from the right of F?

Five students (A, B, C, D, and E) are standing in a line during a school assembly. C is standing exactly behind D. E is not standing behind B. A is standing ahead of C but not ahead of B. If 'behind' means being exactly next to someone's back and 'ahead' means anywhere in front of someone, who among the five students is standing at the third position from the front?
