Learn each meaning in context as you come across it. Learning ten meanings for one word is much the same as learning ten words with one meaning each--the only difference is that all ten words are spelled the same. There's no reason you need to memorize every sense of a word the first time you come across it.
For words with a great deal of meanings, one strategy is to break them down into groups. It's easier to remember three groups of three meanings than nine unrelated meanings, especially if the meanings in each group have something in common.
Finally, try to look at the word and see how the senses developed. Are they all conceptually related? Or perhaps most of them? If you can find a way to relate them to one another, then it'll start to make sense. In other words, you'll be understanding rather than memorizing.
I think you may safely ignore what this author says. There is no substantive difference between an assumption and a supposition.
It is true that assumption is far more common than supposition; but this Google NGram suggests that that is merely historical fashion:
Scholars today are more likely to use assumption than presupposition; a hundred and fifty years ago the opposite was true.
It is also true that you are likely to hear people scorn a proposition as "merely an assumption". But it is equally true that you may to this day hear such propositions scorned as "the merest supposition". Either may be an "unfounded belief"; equally, either may be taken as the starting point of an argument intended to prove that it is false.
And the etymology is wholly irrelevant—to argue otherwise is the etymological fallacy. Etymology tells you where a meaning started, not what it has come to mean today.
These two words are essentially synonymous. They are both significantly different from hypothesis in one critical respect. An assumption or supposition is usually (but not always) taken as a true proposition on which one will base an argument, even if that argument leads in the end to proving the proposition false. But a hypothesis is always advanced as a proposition whose truth is, from the outset, in question. The purpose of the following discourse is to establish whether it is or is not true.

No. If you look up a dictionary, it will tell you that broad means wide in extent or scope. This implies that it is usually used with abstract concepts such as a project or one's knowledge.
My best suggestion here is what bytebuster said: wide-open. There are also less common terms like agape (when used predicatively) or gaping (when used attributively), although gaping usually refers to the open space created by the wide-open door than the door itself. I do, however, suggest you to follow bytebuster's advice unless you are composing serious texts.
