Final answer:
The sentence 'Cheap sweets are empty promises' is likely not the thesis of an essay unless the essay is specifically about consumer goods. A thesis should guide the paper's analysis and structure, which would require the paragraphs to support this statement cohesively.
Step-by-step explanation:
Considering the sentence “Cheap sweets are empty promises,” it seems too specific to function as the thesis of an essay unless the essay is particularly about consumer goods or the food industry. A thesis should present the central argument or main point of an essay, which is then supported and developed through the ensuing paragraphs. When analyzing the effectiveness of a thesis, it is crucial to evaluate how well it provides a focus for analysis and is reflected in the structure and coherence of the paper's organization. If a sentence like “Cheap sweets are empty promises” does establish the goal of an essay, the subsequent paragraphs must logically support this statement with relevant examples, explanations, and consistently maintain this focus throughout. In contrast, if the paragraphs appear rambling and lack connection to the quote, the sentence in question likely does not serve as the essay's thesis.
