Чтобы правильно дополнить предложения инфинитивами, нужно понять контекст каждого предложения и выбрать подходящие формы глаголов. Давайте разберем каждый пункт по очереди:

“Easy” в этом контексте также требует инфинитив с "to", и тут нам подходит "to listen".Sara knows a lot of facts. She is interesting to talk to.
Слово “interesting” требует инфинитив с "to", и в данном случае "to talk" будет уместен.They couldn't afford to buy that car. It was too expensive.
"Afford" также требует инфинитив с "to", и в данном случае подходит "to buy".Alice refused to explain the grammar rule to her younger brother. She had done it twice before.

"Managed" также требует инфинитив с "to", и у нас получается "to carry".I decided to water the flowers in my garden as the soil was very dry.
"Decided" требует инфинитив с "to", значит здесь будет "to water".It was very hot outside and the children wanted to play.
