I thought text data was pretty messy and needed a lot of work.

Totally agree with B! Dates are straightforward.

C seems like a good choice too, event streams are often ready to go!

Wait, are you sure about E? Numeric data usually needs some cleaning.

I think B and E are the ones that need no preprocessing.

I’m pretty confident that numeric data can be used directly, but I’m unsure about the second option.

I feel like text data definitely needs some work before using it, so I’m leaning towards dates and maybe numeric data.

I remember practicing a question like this, and I think event stream data might require some preprocessing.

I think dates with absolute values might not need preprocessing, but I'm not sure about the other one.

Ah, I remember this from the lectures. Dates and event stream data can be used directly without any preprocessing. I'll confidently select those two choices.

This is a tricky one. I know numeric data needs preprocessing, but I'm not sure about the other data types. I'll have to review my notes and try to eliminate the ones that do require preprocessing.

Okay, let me see. Numeric data definitely needs preprocessing, but I'm pretty sure dates and event stream data can be used directly. I'll go with those two options.

Hmm, I'm a bit unsure about this. I think text data and symbolic data might not need preprocessing either, but I'm not totally sure. I'll have to think this through carefully.

I heard you can train a model on random keyboard smashes and it'll perform just as well as the 'correct' data types. Brb, going to try that out and become the next data science superstar.

Wait, you mean I can't just feed the machine learning model a jumble of emojis and expect it to figure things out? Darn, there goes my plan for world domination. Oh well, guess I'll have to settle for B and E.

Definitely B and E. I'm not touching that Twitter data with a 10-foot pole, and event streams sound like a real headache. Give me some good old-fashioned numbers and dates any day!

I'm torn between B and D. Symbolic data with 200 values doesn't sound too bad, but then again, who wants to deal with dates? Maybe I'll just go with my gut and pick B and E.
