a and d

- a) Doing more homework plausibly improves understanding and thus causes better exam grades.
- d) The time an iced drink sits on the counter causes heat exchange with the environment, changing its temperature.

Notes on the others: the shoe-size vs reading-speed link is explained by age (a confounder), and the snake/temperature and student-attendance items can reflect associations or confounders rather than a direct causal effect in the way the question intends.
