I now have papers from London to arrest Mr Fogg.
====================
Q1: What is the part of speech of "to arrest Mr Fogg'? Is it an adverbial phrase or an adjective phrase?
Q2: Does the sentence above mean #1 or #2 in meaning?
1. I now have papers from London so that I can/may arrest Mr Fogg.
2. I now have papers from London which can/will arrest Mr Fogg.
It is an adjective phrase in that modifies "papers", what kind of papers.
It means the first choice, "I now have papers...so that I may arrest Mr. Fogg."
The papers can't make an arrest by themselves, so #2 is wrong.
