A friendly dog met us at the farmgate.

hostile
quiet
understanding
helpful

The correct answer is A. hostile.

A friendly dog would be expected to be happy to see us and would greet us with a wagging tail and a friendly bark. A hostile dog, on the other hand, would be expected to be aggressive and might growl or even bite us.

A quiet dog would be expected to be calm and not make much noise. A helpful dog would be expected to do things like fetch sticks or carry in

groceries. An understanding dog would be expected to be patient and understanding of our mistakes.

In this case, the dog met us at the farmgate, which suggests that it was guarding the property. This is a common behavior for hostile dogs, who are often used as guard dogs. The dog also growled at us, which is another sign of hostility.

Therefore, the most likely answer is that the dog was hostile.
