The chart shows the number of research articles in the prominent journal Physics Review that were written by researchers in Europe during 1983 - 2003 ($$t = 0$$ represents 1983).
Which of the following logistic functions best models the data ( t is the number of years since 1983.) Try to determine the correct model without actually computing data points.

A) $A ( t ) = \frac { 7.0 } { 1 + 5.4 ( 1.2 ) ^ { - t } }$
B) $A ( t ) = \frac { 4.9 } { 1 + 4.3 ( 1.2 ) ^ { - t } }$
C) $A ( t ) = \frac { 4.9 } { 1 + 4.3 ( 0.7 ) ^ { - t } }$
D) $A ( t ) = \frac { 7.0 } { 1 + 5.4 ( 0.7 ) ^ { - t } }$ According to the model you selected, at what percentage was the number of articles growing around 1984 __________%
