Questions about example sentences with, and the definition and usage of "Ren"

A: It’s ambiguous- either one of your ideas could be correct.

A: This tense is OK here, but I think it makes it sound a little too complex and formal. Before I read your answer, I thought the following:
"To be caught in a sandstorm was a terrible experience, there was nothing I could do.". These tenses make sense to me, "to be caught in a sandstorm" acts as a subject, and then "there was nothing I could do" is another way of saying "I couldn't do anything", which is just simple past tense, I think. [English speakers don't usually understand grammar rules very well!!]
