James: 'I saw Sarah walking past the charity box today. She had a lot of spare change in her hand, but she didn't put anything in.'\nLeo: 'That's very unlike her. She's usually the first to help others. She ________ the box, or she ________ the money for something even more urgent.'

Çözüm Açıklaması
Sarah'nın normalde yardımsever olduğu belirtiliyor. Bu alışılmadık durum karşısında kesin yargılardan (must/can't) ziyade olasılık bildiren 'might not have seen' (görmemiş olabilir) veya 'might have been saving' (başka bir şey için biriktiriyor olabilir) ifadeleri nezaket ve mantık çerçevesinde daha uygundur.
