The answer effectively uses a variety of sentence structures, including simple, compound, and complex sentences, which enhances the fluency and coherence of the speech. For example, "The process of making Zongzi is quite intricate, involving soaking the sticky rice, marinating the meat or other fillings, and then wrapping everything carefully in bamboo leaves." This sentence combines multiple actions using gerunds and conjunctions. The use of present simple tense to describe general facts and habits is appropriate, as seen in "We usually eat Zongzi during the Dragon Boat Festival." The answer also includes past tense to describe personal experiences, such as "My grandmother used to make them by hand."
