Question

The lecture was delivered by Professor Aksoy, ---- work on soil chemistry had shaped the entire field.

Accepted Answer

whose — Boşluktan sonra bir isim ('work') geliyor ve bu iş profesöre aittir; sahiplik bildiren 'whose' gerekir. 'Who' kendisinden hemen sonra fiil ister, isim değil. Ayrıca virgülle ayrılmış ek bilgi cümlelerinde 'that' hiçbir zaman kullanılmaz.
