Thanks for checking this. Here's my problem:
This access to new insights and increased knowledge are
usually unavailable until the physical act of writing begins.
I'm troubled by two ways of breaking up the sentence.
1) This access to new insights and increased knowledge are usually unavailable until the physical act of writing begins.
2) This access to new insights and increased knowledge are usually unavailable until the physical act of writing begins.
That is to say, I'm not sure what the adverb 'usually' really modify. Is it simply 'unavailable' or is it 'unavaiable until the physical act of writing begins'?
Let's say that the word 'usually' represents a probability of 80%. Now the first interpretation says that there is a 80% probability that
the access remains unavailable until the act begins is true. The other 20% probability may include cases in which
the access becomes available before the act begins, but it may also include cases in which
the access remains unavailable even after the act begins
The second says that until the physical act of writing begins, the probability of the access being unavailable is 80%. Therefore, the other 20% probability include cases in which the access becomes avaiable.
Thank you!
