As its sales of computer products have surpassed those of measuring instruments, the company has become increasingly willing to compete for the mass market sales it would in the past have conceded to rivals.
I was able to choose the correct answer but I have a different question here.
Subordinate Clause: As its sales of computer products have surpassed those of measuring instruments
Main Clause: the company has become increasingly willing to compete for the mass market sales
Extra clause/Dependent: it would in the past have conceded to rivals.
My question is how the main clause and extra/dependent clause are joined without any subordinate conjunction such as that etc.
