Today's weather is worse than yesterday's."

When comparing two things (today's weather vs. yesterday's), you use the comparative form of adjectives.

The comparative form of "bad" is "worse".

"Bore" is unrelated and refers to boredom, not weather.

"Bad" is the base form and not suitable in a comparative sentence.

Explanation

She wished she had bought the new car.

اس کی خواہش تھی کہ اس نے نئی کار خریدی ہو۔

"She wished" refers to a past regret, so the past perfect "had bought" is correct.

Explanation

 "She is a nice girl." is a positive statement.

The auxiliary verb here is "is" (from "is a nice girl").

To form the tag question, we invert the auxiliary verb and add the corresponding pronoun.

Thus, the tag question is:

"She is a nice girl, isn't she?"

This structure follows the rule: positive statement + negative tag.

Therefore, the correct answer is:  Isn't she

Explanation

 "Many newspaper readers are bothered by the superstitious writing style of editorials."

"Bothered" means disturbed or irritated, which fits the context of how readers feel about the writing style.

"Belied" means to contradict or give a false impression, which doesn’t fit here.

"Bereaved" means to have lost someone, usually through death, and it doesn't apply in this context.
