ответ: couldn’t
Объяснение: В английском языке есть такое понятие как согласование времён. В данном случае там глагол killed в времени. Соотвественно остаются только времена: could или couldn’t. А чтоб определить какой вариант подходит нужно глянуть дальше по-смыслу и плюс можно обратить внимание на any, так как это своего рода подсказка (any употребляется с отрицанием: I can solve some problems in the textbook. I can’t solve any problems in the text book). И по смыслу там сказано что он не нашёл никаких яиц и соответсвенно становился все беднее и беднее. Таким образом мы выходим на couldn’t.
