I feel like we had a similar question on the last practice exam, and I think the correct approach was to use the filter method effectively, like in option C.

I think option C looks familiar; it uses RDDs and seems to follow the logic we discussed in class about aggregating data.

I'm a bit unsure about this one. The wording of the question and answer choices is a little confusing. I'll need to re-read it a few times to make sure I fully understand the concept before selecting an answer.

Okay, let me break this down. The Act is meant to provide transparency in public authorities, so I'm guessing it wouldn't cover the high courts or state legislatures since they have their own processes. I'll go with B for now, but I'm not 100% sure.

I'm not sure, but I think option B might also work because it selects the name and stay time for female netizens spending more than two hours online.
