@lindsayo I assume it's a mistake hope someone at 7sage can clarify

same boat here, 162 on my last lsat. to get into t30s im assuming 175+ is the only thing that will guarantee at least some admissions at that level?

@LucyB4 I was thinking about this as well, from what I understand the subject and object DO change.

In the sentence we looked at two lessons ago for example the subject and object does change in passive voice. "developments (s) helped archeologists (o)" vs archeologists (s) were helped by developments (verb modifier)

"New developments in satellite hardware and artificial intelligence imaging software helped archeologists discover tombs of pharaohs once thought to be mythical."

Important thing to note, its not either/or, its both. The phrases after "by" are the object of the preposition by, however in the entire sentence's context, the phrase modifies the verb.

Hope that helps, feel free to correct me
