a) Because of the 1 at r2c2, either r1c5 or r3c5 must be 1 -- and therefore, no other cell in column 5 may have a 1.

b) r7c5 and r9c5 must be either 4, 6 or 9 (not 1, from statement (a))

c) r6c5 is in the same row, column or box with a 2, 3, 4, 5, 7 and 8 -- and it cannot be a 1 from (a) -- so it must be a 6 or 9.

d) The cells r679c5 that must contain the digits 4, 6 and 9 in some order.

e) This means that r5c5 cannot contain a 4, 6 or 9 -- leaving only one cell in box 5 that can hold a 4 -- r5c6.

HOWEVER, this is not the hardest part of this puzzle. You probably won't be able to solve it without using at least some if not complete pencil marks.

Current postion after r5c6=4:
