Select the best answer for the question. 6. This question is based on the following passage.
Both Seagulls and wild geese are large birds. They're also similar in that both kinds of
birds can fly over great
distances. On the other hand, seagulls are scavengers, while
wild geese aren't. Seagulls, for example, are often found around garbage dumps.
Geese, however, feed on things like seeds and insects. Another important difference
between the two kinds of birds is that geese fly on long annual migrations of well over
1,000 miles. Seagulls will migrate far inland to search for food. However, they don't
follow seasonal patterns of migration like wild geese.
