In the essay writing, the introduction part should end with a ________.a.some fact and evidenceb.Thesis statementc.Supporting argumentd.concluding sentence

In essay writing, the introduction typically concludes with a specific statement that sets the direction for the rest of the essay. Let’s analyze the options provided:

1. Some fact and evidence - While facts and evidence are crucial for supporting claims, they typically appear in the body of the essay rather than concluding the introduction.

2. Thesis statement - This option refers to the central argument or claim of the essay. A thesis statement outlines what the writer intends to argue or discuss and often concludes the introduction. This is generally the best choice for this question.

3. Supporting argument - Supporting arguments are used in the body paragraphs of the essay to back up the thesis statement. They would not typically conclude the introduction.

4. Concluding sentence - This is a term more commonly associated with the body of the essay, summarizing key points rather than serving as a closing statement in the introduction.

Given this analysis, the correct answer is b. Thesis statement. The thesis statement serves as a guiding framework for the entire essay, indicating the main point or argument the writer will develop.
