Golden retrievers are more loyal, friendly, and smart than a pitbull, but on the other hand, Pitbulls are more protective, so it depends why you want the dog, if you want a guard dog than a pitbull would suit you, but if you want a companion dog then get a golden retriever, I would take the Golden retreiever.
Cannot is formal, while can't in informal.
"Cannot" and "can not" are interchangeable, but when you are asking question for example:
"why can't I...", you can also say "why can I not..." (which is more formal), but you can't say "why cannot I..."
The rhyming scheme is AA BB CC DD
That is because Brain and Remain rhyme, so they are AA. True and View rhyme so they are BB. Trudge and Judge are CC, and Small and Call are DD. None of them repeat the rhyme of the previous verses so they are each given a separate pair of letters.
