A. Importance, <em>hope it helps</em>
<u>Answer</u>:
The sentence "C: Tony picked up the tab for our dinner last night.
" is written using informal language.
<u>Explanation</u>:
Informal language means the one that is spoken casually and used amongst family and friends. It is not a formal language used in offices and businesses.
Option C has a word ‘tab’ which is a casual word for ‘tablet’. So, this is a sentence in informal language. Other options have all formal words used. For example, ‘detoured’ in option A. Option B refers to fire drill. Option D refers to the menu that was ‘impressive’.
Its past, "have experienced" meaning they've already been through it
The correct answer is - Both served as a stage for political and social issues of their time period.
A is incorrect because there were many delays while building the theater. B is incorrect because the Roman Forum is obviously not located in England. D is incorrect because the poor could enter the Globe Theater, they just couldn't afford good seats.
This leaves us with option C - politics and social issues were usually discussed at the Forum, whereas there were many political plays performed at the Theater.
