What you wrote is great but I do want to give you some tips.
1) Do you know what Subtle means? You need to know what words mean before you write it down. Subtle - especially of a change or distinction. Here is an example - It was a subtle of gray.
Other than that the text you wrote is amazing! Good Job! I guarantee you will get an A+! Plus you so deserve an A+!!!
Thankyou magical genie that's out of the lamp !!!!!
Answer:
d. external; internal
Explanation:
After the first science test, she attributed the reason of her bad grade to an external source: the teacher's competence.
After the second test, she attributed the reason of her good grade to an internal source: herself, her intelligence and her proficiency in science.
Was she right? I don't think so... because if the teacher was the cause of the failing of the first test, how come the same teacher produced a whole different result on the second test?
