Answer the following questions based on the information given below. Eight doors F, G, H, I, J, K, L, and M have different lengths. Only three doors are longer than
I. The length of only two doors is less than K. I is 20cm longer than K, whose length is 380cm. G is longer than F but not the longest. H is shorter than F. M is shorter than J, which is shorter than R. The difference in the length of I and L is 120cm. How many doors are shorter than L?

Only three doors are longer than I. The length of only two doors is less than K. _____  > _____  >  _____  >  I  >  _____  >  K  >  _____  >  _____   I is 20cm longer than K, whose length is 380cm. _____  > _____  >  _____  >  I(400)  >  _____  >  K (380) >  _____  >  _____   G is longer than F but not the longest. H is shorter than F. M is shorter than J, which is shorter than H. _____  > G  >  F  >  I(400)  >  H  >  K (380) >  J  >  M     The difference in the length of I and L is 120cm. L  > G  >  F  >  I(400)  >  H  >  K (380) >  J  >  M   The final arrangement is as follows: L (520cm) > G > F > I (400cm) > H > K (380cm) > J > M
