Question number 7 states that we should choose 2 options, however, there are more choices, choice H is also valid.

Note that this question already has errata attached: https://www.selikoff.net/ocp11-1/ (#7 – the question should not contain “to dog”)

The review question asks:

Suppose module puppy depends on module dog and module dog depends on module animal. Which two lines allow module puppy to access the animal.behavior package in module animal? (Choose two.) - redacted with 7/4/20 errata in mind:

module animal {
  exports animal.behavior;
}
module dog {
  ___ animal; // line S
}
module puppy {
  ___ dog; // line T
}

This code should also work:

module animal {
  exports animal.behavior;
}
module dog {
  requires transitive animal; // line S
}
module puppy {
  requires transitive dog; // line T
}

Interestingly, option H is not discussed at all in Answers to review question, which is also a candidate for another errata!

[Jeanne Boyarsky]

I don't consider option H an errata. It does work, but it is more broad than necessary. And since the question says "choose two", it should be the best two.

Ok, thanks for the tip
