Study the following information carefully and answer the questions given below :
Eight persons — E, F, G, H, W, X, Y and Z — are sitting in two parallel rows containing four persons each. E, F, G and H are sitting in row–1 facing north and W, X, Y and Z are sitting in row–2 facing south (but not necessarily in the same order.) Thus, each person sitting in row – 1 faces another person sitting in row – 2. Each of the two rows consists of one Doctor, one Engineer, one Pilot and one Scientist (but not necessarily in the same order).
The Doctor of row–1 sits second to the right of H. X faces one of the immediate neighbours of H. Only one person sits between the X and the Scientist.
The one who faces the Scientist of row – 2 is an immediate neighbour of E. Only one person sits between E and the Pilot.
W sits second to the right of Z. Y does not face G. The Scientist of row–1 faces the Engineer of row – 2.
G faces one of the immediate neighbours of the Doctor of row–2. The Doctor of row–2 does not sit at any of the extreme ends of the line. Z is not a Doctor
