"I wandered lonely as a cloud" is comparing a cloud directing to a persons feeling. This would be a simile.
As for this problem concerning about a transition between sentences and paragraphs, the most probable and most likely to be the answer out of the options presented would be the third one which is a bridge.
A transition serves as a bridge between sentences and paragraphs. Though they create a divide between them, these transitions do not necessarily indicate that the divide is to cause to present that the two aren't connected to each other. A summary and introduction wouldn't do since a transition functions more and effectively between sentences and paragraphs.
True. nonconformist preaching were against the law.
Tom doesn't like attending church, he endures it, and is restive all through it. He has gone many times though, he knows the prayer so well that his ear detects any small change made by the clergyman from the regular route of the prayer. Tom doesn't like change because he considers any changes to the normal prayer unfair, and scoundrelly.
