Students are constructing models for how gasoline prices change. Maria's model has very realistic assumptions and is quite complex. Anna's model is less complicated and less realistic. Maria's model correctly predicts gas price increases 55% of the time. Anna's model predicts correctly 75% of the time. On the basis of the usefulness of the model, which student's model will get the higher grade and why?

Anna

Explanation:

Overall the best model is the one which can best predict and forecast. Overall, the two students are trying to predict the prices of gasoline. Anna's model predicts correctly 75% of the time, and Maria's model can predict 55% of the time. According to the track record, Anna is likely to get higher grades because she has a better prediction record.

the correct answer would be b, when, queen, calder hall and london.

explanation:

we always capitalize words when a paragraph or sentence is starting, when an important name is used, when a place is being written, or simply when a noun is used, etc. so in this sentence, sentence is starting from 'when', so it will be written in capital letters. secondly, queen is considered to be an important person, so it will also be written in capital letter. next, the name of the town is mentioned, i-e calder hall, which will also be written in capital letters. in the last,   city name is being used, 'london', which will also be written in capital letters. so option b is the most appropriate one.
