A complex sentence is a sentence that contains one independent clause and at least one dependent clause. To change the given simple sentence into a complex one, we need to introduce a subordinate clause. In the original sentence, "glittering" is an adjective modifying "things". By replacing this adjective with an adjective clause, we form a complex sentence.

Here, "People in general are fond of things" acts as the independent (main) clause, and "which glitter" acts as the dependent (subordinate) adjective clause. The relative pronoun "which" connects the dependent clause to the noun "things" in the main clause, making the entire structure a complex sentence.

To change a negative sentence into an affirmative one without altering its original meaning, it is often necessary to replace the negative expression with an antonym or a phrase that conveys the opposite idea positively. In the given sentence, "do not bother about" expresses a lack of concern or attention. The affirmative equivalent of this phrase, which maintains the same meaning, can be "are indifferent to" or "neglect." This transformation allows the sentence to be grammatically positive while retaining its semantic equivalence to the original negative statement.

A simple sentence contains only one independent clause, meaning it has one subject and one finite verb. The original sentence, "They fade soon and lose their beauty," is a compound sentence because it has two independent clauses ("They fade soon" and "they lose their beauty") joined by the coordinating conjunction "and."

To transform a compound sentence into a simple sentence, we often use a participial phrase, an infinitive phrase, or a prepositional phrase to condense one of the clauses. In this case, "Fading soon" is a present participial phrase modifying "they," which allows "lose" to remain the single finite verb of the main clause.
