What is "big data"?
Student or Learner
In the sentence below, are all the choices fine? It seems to me that "as" fits best because "same" and "as" are used together very often, but the other two also looks fine.
"Using big data, we can now observe humans in the same way [as /in which /that] biologists can observe animals in their natural habitats using cameras, GPS and other recording devices."
Big Data is a mass of data gathered from cellphones, social media or other sources to learn what people are interested in or what they need. It can be useful for market study. It is believed to have huge potential for many other purposes.
This is not my homework. "that" was used in the original passage, but I thought "in which" would also be fine and "as" sounds better to me. I would just like to make sure if I'm on the right track.
