The police officers___the suspicious killing of a diplomant before a renowed businessman____ a couple of days ago. Correct Answer had been investigating/was kille
অতীতের দুটি কাজ before দ্বারা যুক্ত হলে before এর পূর্বে past perfect/past perfect continuous এবং পরে past indefinite tense হয়। সুতরাং শূন্যস্থান দুটিতে had been investigating এবং was killed বসবে।
