Is it encouraged or discouraged to use "IT IS" at the very beginning of a paragraph in formal writing English?. For instance:
It is often argued that study art in school should be mandatory, since kids who study it, boost their qualifications in other fields, because multi-talent students are more likely to learn things easily.
This is the first and introductory paragraph of an essay. Also, it is correct to write the gerund "studying" after "that"??.. Thanks for your response!!.
