Answer:
In lines 10–11 the speaker is referring to the importance of interpreting what is being read. On lines 20–21, the speaker shows that reading interpretation promotes knowledge and that knowledge is often a handicap for the soul.
Explanation:
In lines 10–11 the speaker is referring to the need that people have to interpret and understand what is being read, this is because if a person just reads, he is stuck with earthly life, he is limited to an environment, contained. However, the interpretation of reading makes the individual see beyond words and let go of this limitation.
However, once the reading has been interpreted, the individual gains knowledge, becomes detached from ignorance and is able to see things he did not see before. The problem is that this is often a disadvantage, showing that ignorance was a paradise, which was lost with the arrival of knowledge. This can be seen on lines 20–21.
Mercutio doesn't have any particular thoughts about women or fate and destiny. He is young and just having fun. He doesn't take things seriously. Although he is reckless, he does things and control them. He creates his destiny - that until his fate is taken out of his control.
One way to fix that sentence is to switch around the two phrases used; 'My mother and father are both scientists' and 'It must have been my destiny to become interested in biology.'
It must have been my destiny to spark an interest in Biology, as my mother and father are both scientists.
That's a way to fix that sentence used in your question.
Also, 'destiny' was spelled incorrectly.
This sentence may seem run on if you don't place a conjunction between the two phrases, or if the phrases are not switched.
If the sentence is to be used with a conjunction, it may end up like this....
My mother and father are both scientists, so it must have been my destiny to become interested in biology.
Or, you may just use a period, to change the two phrases used into two separate sentences.
Like this;
My mother and father are both scientists. For that reason, it must have been my destiny to become interested in biology.
ALSO, as you can see above, I have added a few words to the last sentence. Those three words, 'For that reason', give closure to the two sentences.
Hope this helped!
