Structural grammar became popular fifty years before transformational grammar. t/f

The answer would be false. Although structural grammar became popular before transformational grammar, there was not a gap of fifty years between them. Structural grammar developed in the 1930s to the 1950s, and is generally attributed to Ferdinand de Saussure. Transformational grammar, which is attributed to the linguist Noam Chomsky, originated somewhat later, in 1957. So, they are not that far apart. Hope this helps.
