I think that the answer is B. Brackets can indicate a change in verb tense
Hi. You have not informed the web which Travis is using. This makes it impossible for your question to be answered. However, after searching for your question on the internet, I was able to find another question just like yours, which asked you to present, what information Travis could use to present the main causes of the fire, on the web. If that's the case for you, I hope the answer below can help you.
Answer and Explanation:
For the main causes of the fire, Travis can show that firefighters were sent to the wrong place and that the number of wooden buildings in the city stimulated the fire.
The great Chicago Fire was a tragedy, where almost the entire territory of Chicago was set on fire, leaving many dead, injured and homeless. One of the major factors that made the fire take such large proportions was the amount of wooden buildings present in the territory. Wood was the raw material of practically all houses, buildings and even roads and all this wood served as food for the fire, allowing it to spread quickly. The firefighters' delay also contributed to the fire, as they were sent to the wrong location, which greatly delayed the rescue and fire fighting.
