I'm trying to find, which of the following sentences is correct?
A) We try to highlight how they contribute to investigate their importance.
B) We try to highlight how they contribute to investigating their importance.
I found that both cases were used frequently in formal writing.
Edited:
Sources for each case:
For A: "Their multifaceted nature means that there are very many routes to investigating their importance for understanding social change" in "A lineage for contemporary inter-city studies" book.
B: "More factors are analysed to investigate their importance in scoring from shots and shot probabilities" in "Applications of logistic regression to shots at goal at association football" book.
