Part 1
Text structure is how you organize your information. For example, you may want to organize it in a cause/effect scenario, or using chronological order. For example, a text structure can take on the form of such:
First, Japan surprised attack Pearl Harbor even when they were trying to hold peace conferences with the USA as a promise that they would hold the US's neutrality. This leads to President Roosevelt's famous "Day of Infamy" speech, which led to the US declaring war on the Axis Powers, and the internment of Americans with Japanese Ancestry (Nisei and Issei). Finally, the Issei's had to endure harsh treatments in the camps, and were fin
ally let out of the camps following the Japanese surrender.
While this does not give the complete picture, it gives a feeling of a chronological order (in which after the attack of Pearl Harbor, it led to the Infamy speech, which led to the internment of Japanese Americans). It also gives a cause and effect (because of the attack, there is consequence for the Japanese Americans). This is just one of the structures you can use, but of course there are many more examples you can give.
Part 2
In the passage no gumption it shows the presence of a descriptive structure and describes and idea and helps explain the characters by depicting them to the reader. To build a fire shows sequential structure by explaining he ideas in a time order. The story also shows that his actions led up to his hardships because of his decisions. And do it yourself. ;)
Hope this helps!!!
The correct answer is all navigation near coral reefs, including anchorages and vessel routing that keep their safe distance and frequency at a minimum and respect all laws of utilization of marine resources and safe transit are not a threat to coral reefs. The threats would be excessive and unsafe navigation, abusive utilization of marine resources, pollution and hazardous material spills.
The tense is all mixed up, but it looks like present is used most often, so "emitted" should be changed to "emits" and "pulled" should be changed to "pulls." I can't see the entire paragraph so just make sure that's consistent.
You don't need a comma in "running towards us with the fire extinguisher."
"Your mother and me" should be "Your mother and I." For reference try taking our "your mother" - it sounds pretty silly to say "me thinks" unless you're in the 1600s, right? And it should be "think" instead of "thinks."
