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

Context:

The Second is the second studio album by Canadian-American rock band Steppenwolf, released in October 1968 on ABC Dunhill Records. The album contains one of Steppenwolf's most famous songs, "Magic Carpet Ride". The background of the original ABC LP cover was a shiny "foil", in contrast to later (MCA Records) LP issues and the modern CD sleeve.

Hypothesis: In 1970 Steppenwolf had the highest grossing tour.
