Final answer:
The most objective sentence revision Myra can choose is the one that states the program will draw attention to the city and neutrally acknowledges that some citizens may try to boycott it, without using subjective language.
Step-by-step explanation:
To revise the sentence so that Myra uses objective language, she should choose the option that avoids subjective descriptors and potential biases. The most objective version among the provided choices is: "This program will draw attention to our city. Some citizens may be difficult to convince and will try to boycott the program." This version omits any subjective adjectives like 'clever', 'cutting edge', or 'difficult' and refrains from assuming the actions or intentions of the citizens who may oppose the program.
