Study the following information to answer the given questions: 
Eight persons – A, B, C, D, E, F, G and H are sitting in a row but not necessarily in same order. Some of them are facing North and others South.
A and B are facing different directions. Similarly E and H are facing different directions. C sits four places away from D and sits at one end of the row and both are facing South.
The number of persons sitting to the right of F is one less than the number of persons sitting to the right of E. The persons sitting at the ends are facing the same direction. Exactly two persons are sitting between A and C. G sits to the immediate right of B. E sits third to the left of D, who is to the immediate right of F

1. Explanation: 
   Start with 1st point, taking C at any of extreme end. Let us take C at left end, then D is four places away, both facing south. Now two places between A and C. Now go at last point, and place E and F. Arrangement is
   C _ _ A D F _ E
   Now it is given that number of persons sitting to the right of F is one less than the number of persons sitting to the right of E. But in above arrangement this is not correct.
   Lets take C at right end, and continue like above, we get final arrangement as
