碰到一些英文的閱讀問題想請教各位，謝謝。
1. And I basically just draft right behind what could be a conga line of F150s
with chainsaws and use them to cut a path back to my study sites.”
1-a. 這邊的draft right behind是指他計畫並全力支持這件事情嗎?
1-b. cogna line只知道是一種康加舞蹈，那跟F150s，還有後面的電鋸又有什麼關係呢?
2. The spiders come in two personality types: docile and aggressive.
2-a. 在這邊的come in 是意旨演變成的意思嗎? 還是我應該要理解成
The spiders come in two personality types?
蜘蛛演變成兩種不同的性質
3. 因為問版的問題種類比較多，有人可以推薦英文閱讀文法的討論區嗎? 謝謝。
