<span>C) to discuss the infallibility of memory to recall facts correctly from the past
The narrator in this is talking about an important memory from his childhood, but he is nervous when he thinks about how the memory might be 'marred' or changed from the innocence of youth. He remembers the place but hopes that it has remained as pure as he felt it was from his childhood. </span>
im not sure what excerpt you are referring to but please explain further and ill be happy to help:)
Williams show that the wheelbarrow is an essential part of life on a farm through the phrase: "so much depends upon" it leads the readers to infere the importance of the wheelbarrow.
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!
