#grep "th[aeo][[:space:]tns][[:space:]e]" # doesn't exlucde 'thou' and doesn't seem to include 'those'
#grep -E "(the|then|that|those)" # shows up as wrong answer
#grep -iE "(the|then|that|those)" # this works initially but fails 1 test case when submitted
#grep -E "(being|the|that|those)" # passes initially but fails both test cases when submitted
grep -wiE "(the|then|that|those)" # passes intitally and passes all submissions
