The rest was just rubbish.
1.
Random disparate pairs of words, and swap initials. I guarantee you that no-one got this.
2.
Swapping breakfast, with any of the other meals, results in at least 4 solutions - totally defeating the purpose of trying to solve them in the first place.
Go back to the beginning, and try and stay within the criteria of the game.

Well, I got the letter swap group - though it seemed like a weird thing to do.
However, you'll accept London hill, yet not "hills in london"? wtf?

Sorry but this wasn't great. The word swaps just aren't a thing!
