The following exercise is excerpted from 'The College Pandas SAT Writing Advanced Guide and Workbook for the New SAT' book:
Choose the right option to replace the underline portion.
- SAT scores are extremely important. They are only part of the application, however, grades and teacher recommendations are other factors that colleges take into account.
a) NO CHANGE
b) application however grades
c) application. However, grades
d) application, However. Grades
The book model answer says (d) is the right option. I've never seen 'however' punctuated like that! What's your opinion?
Is it supposed to be "... and teacher's recommendations..."?
