Hello. You did not ask the question to which this text refers, which makes it impossible for me to give you an answer. However, when searching the internet, I found a question that used that same text and asked what was the verb tense of the text and what was the meaning of the phrase ‘this green flooring’. If that's your case, I hope the answer below can help you.
The verb tense of the text in the first sentence is Simple Past. Since the verbs "had landed" have an action performed in the past and that has been completely completed. However, the second sentence presents the past tense Past Perfect Continuous, as it presents an action that happened in the past before another action happened, since we can see that the characters waved before starting to call out stridently.
The phrase "this green flooring" refers to the characters stepping on a floor with vegetation and therefore stepping on a "green flooring."

2. False
Many events can have more than one cause and more than one effect. Effects, especially, can be high in number because one cause can set off a chain of events that affect a lot of different people.
Apostrophe and Simile i think.
