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.
