When writing for academia, you’ll always want to be as precise as possible. Thus, you’ll want to stay away from generalizations, vague words, as well as relative words (words that can mean different things to different people). For instance, in looking at the sentence, there are a couple of instances where things could more precise.
“I have read a bunch…” – How much is a bunch? Here, an exact number would be the best manner to be precise. For instance, “I have 23…”
“…informative texts…” – What type of informative texts? Here, by being precise, the credibility could be affected. Scholarly journals? Tabloids? Again, it is always best to be specific.
“…on the topic you just mentioned…” – Here, to be precise, it would be best to reiterate the topic. What topic is that?
