Answer:
an assumption that the decision could have resulted in the further eroding of free speech rights to citizens
Step-by-step explanation:
" The Supreme Court has decided that free speech rights are more important than helping parents keep violent material away from children." In this version, the present perfect has been used, so the focus has been set on the effect of the action denoted by the verb: to decide. The decicion has been made : free speech is more important than helping parents . The original sentences uses the future, so it has not set the focus on a final decision but on the probabilties of making that decision. It is a speculative idea, therefore a decision against freedon of speech may be made.
