Read the sentence and answer the following question: i like many things about scientific subjects, mainly the observations and data studies. which revision would make this sentence more precise?

The word “things” should be replaced by something more specific in order to make the sentence more precise. You should avoid general words and imprecise vocabulary. You can also consider being more specific with the phrase “scientific subjects” (which ones are you referring to?). Thus,  the sentence will be more precise and more interesting to read. It is worth mentioning that this type of “vague” words are not academic since they do not follow the precise register of an academic writing and can consequently generate obstacles and misunderstandings.

the best asnwer is b "les encantan los juguetes nuevos" because you are talking about them

what are you asking? this is gibberish.
