First sentence: Why this is the first line? This paragraph is the first sentence because it asks a question about what to do after finishing a research project. It introduces the main topic without going into details. This follows the rule of Topic Sentence. Why other lines are not chosen? The other paragraphs are not chosen because they do not stand alone. For example, 'I know you won’t want to hear this...' starts with a pronoun and refers back to something not mentioned. 'In fact, this final stage...' uses 'In fact' which suggests it is not the start. 'Developing a good, effective and concise report...' is specific and does not introduce the topic. 'And, in many research projects...' starts with a conjunction and is not independent.

Concluding sentence: Why this is the last line? This paragraph is the last sentence because it wraps up the discussion about writing reports. It gives a final thought on the need for different reports, which reflects the main theme of the text.
