It will become ambiguous if we frame the issue as "the stratification between the rich and the poor."
For example, "The reality and the problem of medical welfare service for the single-mother families" may be a better way to approach the issue.

"It will become ambiguous if we frame the issue as"＝「案件を～のように捉えると曖昧になる」
" 'the stratification between the rich and the poor.' "＝「貧富の格差。」
"For example,"＝「例えば、」
" 'The reality and the problem of medical welfare service for the single-mother families.' "=「母子家庭の医療福祉サービスの事情と課題」
"may be a better way to approach the issue."＝「の方が課題に対して良いアプローチかもしれない。」
