Final answer:
The student was asked to identify and correct errors in a provided paragraph. The errors 'provideda' and 'in an altitude' were corrected to 'provided' and 'at an altitude,' respectively, and 'boasts of' was noted to be optionally corrected to 'boasts'.
Step-by-step explanation:
The paragraph provided requires corrections for each line. Below are the errors identified along with their corrections:
- Line a: The error is 'provideda'. It should be corrected to 'provided'.
- Line b: The error is the phrase 'in an altitude'. It should be corrected to 'at an altitude'.
- Line c: There is no error in this line, so no correction is needed.
- Line d: The error is 'boasts of'. While this is technically acceptable in British English, in American English it is often corrected to simply 'boasts'.
