Can we draw the following hypothesis from the context (see options)? 

Context:

Anthony and the Camp is a dance music group led by producer Anthony Malloy. The group also consists of Crawford Peterson, Henley Goddard and Linden Aaron. Malloy, who already had a number-one hit on the Hot Dance Music/Club Play chart with his former group Temper, hit the top spot again with the Camp in 1986 with the song "What I Like".

Hypothesis: Malloy joined the Camp prior to 1986.
