Paragraph list

Cameras help autonomous vehicles read street signs and the color of traffic lights.
The startup, which has raised $36 million in seed-stage funding so far, built its LiDAR systems from scratch.
But LIDAR’s, aka light detection and ranging systems, do the important work of sensing and helping cars avoid obstacles, whether that’s a fallen tree, drunk driver, or a child running out into the road.
Now, a startup called Luminar Technologies Inc., is unveiling a high-resolution LiDAR sensor that was five years in the making.

First sentence: Why this is the first line? This paragraph is the first sentence because it introduces the main topic of the text. It talks about cameras and their role in autonomous vehicles. This is a general statement that does not need other sentences for context. It does not start with a conjunction or use pronouns. Why other lines are not chosen? Paragraph 2 starts with 'But', which is a conjunction, so it cannot be the first sentence. Paragraph 3 uses 'Now', which suggests it is not the start. Paragraph 4 uses 'The startup', which refers to something already mentioned, so it cannot be independent.

Concluding sentence: Why this is the last line? This paragraph is the last sentence because it wraps up the information about the startup. It gives a summary of the startup's achievements and funding. It concludes the discussion about the technology and the company.

Paragraph pairs:

  • Pair 1 (Paragraph 1 → Paragraph 2): Paragraph 2 connects with Paragraph 1 because it uses the word 'But'. This shows a contrast between cameras and LIDAR systems. It continues the topic of technology in autonomous vehicles.
  • Pair 2 (Paragraph 2 → Paragraph 3): Paragraph 3 connects with Paragraph 2 because it starts with 'Now'. This shows that it is talking about a new development in LIDAR technology. It continues the discussion about LIDAR systems.
  • Pair 3 (Paragraph 3 → Paragraph 4): Paragraph 4 connects with Paragraph 3 because it talks about the same startup, Luminar Technologies Inc. It gives more details about the startup and its funding, which is related to the new sensor.
