The point of view used in "Was it a dream?" is the one of a man totally in love as to the point that he could not conceive life without his loved.
If he had loved her in a more consciously way he might have been able to deal with the fact of her illness and probably things would have been different.
The author communicates feelings about love relationships by describing in detail the many sensations about his loved woman. It was a love almost crazy, desperate and like if nothing else in the world existed.
This kind of feeling is really very risky since the person centers life in that love and if love breaks or one of the couple dies simply life ends up.
The central idea of the passage mentioned is the differences the Pilgrims had with the Church of England. It is how it is mentioned in the passage that their Englishmen forefathers where so religious that they devote their life unto the Lord if anything would have happened to them. The pilgrims in turn told that when the Lord heard them, He just looked over their adversity but did not specifically say if the Lord has ever helped them. It showed that the Pilgrims where furious about the loyalty to the Englishmen forefathers that they in turn do not want to believe what they believed in before. That they can do it without turning themselves to the traditional way of thinking.

The main idea: Rain barrels are easy to install and use.
This idea needs to be supported with a sentence that relates in a logical and coherent way with it's content. In other words the following sentences need to demonstrate the reasons they barrel are cheap and easy to install, examples and facts can be given.
In the sentence chosen the author says that he made his own barrel, in this way he tries to show us that anyone can do it, an expert is not needed to perform this task, therefore they are "easy to install and use". By mentioning the low price he makes an implied relation, we associate cheap things with simple things, if the barrel was a complicated thing to use they would probably be more expensive.
The other options given just give general information related to barrels but are not able to connect with the main idea.
