Answer:
Q. 1 C). Tricks meant to be funny may offend others.
Q. 2. "Announcer 1: The pranksters feel the joke has gone too far, and Olivia is too angry with them."
Explanation:
Q.1 As per the context of 'Twelfth Night,' the central idea that is being conveyed would be that 'Tricks intended to have fun can not be funny for everyone and may distress others.' The characters impersonate themselves as different persons(Viola as 'Cesario, the page-boy,' Feste as Topas, the scholar,' etc. ') in order to trick the ones around them which displeases them and evokes unexpected responses. Thus, <u>option C</u> is the correct answer.
Q.2 The detail that most adequately backs the central idea conveyed in part A would be Announcer 1's statement declaring that 'The pranksters' realization that their tricks have crossed the limits and leading Olivia's excessive anger towards him.' This supports and substantiates the above-mentioned idea that the tricks aiming to evoke laughter sometimes offend and upset people and their emotions as well.
