Fixed-response questions

learnr::question("Which planet do we live on?",
         answer("Mars", correct = FALSE),
         answer("Earth", correct = TRUE,  message = "Good job Earthling!"),
         answer("Saturn",  correct = FALSE),
         allow_retry = TRUE,
         random_answer_order = TRUE
)

Hours in 2020

Use the box below to calculate how many hours 2020 has.

**Hint:** Remember 2020 is a leap year (if you haven't noticed yet :-)) and it has 366 days. Each day has 24 hours. Therefore `366 * 24` should be the correct answer.

gradethis::grade_result(
  fail_if( ~ .result != 8784, "Result should have been 366 * 24 = 8784"),
  pass_if(~ TRUE, "Well done!"),
  glue_correct = "{.message}"
)

Multiple selections in multiple choice

learnr::question("Which of these are countries? (Select ALL that apply)",
         answer("California", correct = FALSE),
         answer("France", correct = TRUE, message = "Good job Earthling!"),  
         answer("China",  correct = TRUE),
         random_answer_order = TRUE,
         allow_retry = TRUE,
         options = list(foobar = "Flag")
)
