First sentence: Why this is the first line? This paragraph is the first sentence because it introduces the main topic of the text. It gives a broad overview of technology and its effects. 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, "For example, phones are known to cause problems due to radiation" starts with 'For example,' which is a conjunction. This means it needs more context. Other sentences like "Some people also make phone calls while driving, which cause incidents" and "But we cannot deny the advantages of technology, for example, phones have brought the world closer" also start with phrases that need prior information. Lastly, "I think it all boils down to how we use a particular technology" is an opinion and does not introduce the topic.

Concluding sentence: Why this is the last line? This paragraph is the last sentence because it gives a final thought on the topic. It wraps up the discussion about technology and its use. This follows the rule of Summary Style.
