70% to pass

Under the U.S. Aids to Navigation System on the Western Rivers, a daymark on the right descending bank will _______________.

A have an odd number
B have yellow retro-reflective markings
C be green
D indicate the gage reading
AI Explanation

The correct answer is C) be green. Under the U.S. Aids to Navigation System on the Western Rivers, daymarks on the right descending bank are green in color. This is because the green daymarks indicate the right side of the navigable channel when traveling downstream. The green color helps mariners identify the proper side of the channel to follow. The other answer choices are incorrect because: A) odd number daymarks are used on the left descending bank, not the right; B) yellow retro-reflective markings are not a requirement for daymarks on the Western Rivers; and D) the gage reading is not indicated by the color or appearance of the daymark itself.
