The answer is D - present perfect tense. A would be - gave. B would be - gives. C would be - had given.
The answer is C I hope I’m not too late
“The speed limit should be lowered for safety reasons” would be the best answer. All of the other sentences are too informal. When writing an opinion piece you want to have somewhat of a conversational tone but you shouldn’t use words like “totes” and “gotta”. I’m the end, it is a formal paper stating your opinion and should be professional.
I believe that “chat” is stressed/accented and “el” is unstressed. Similar to the word “present,” where emphasis/accent is placed on “pres.” Hope this helps!
