Based on the passage about tides, when would a fisherman expect the greatest difference between high and low water?
Read the passage: The rise and fall of the sea along coastlines is caused mainly by the gravitational pull of the Moon. As the Earth rotates, most coasts experience two high tides and two low tides roughly every day. The Sun also pulls on the oceans, though its effect is less than half that of the Moon because it is so much farther away. When the Sun, Moon and Earth line up, at new moon and full moon, their pulls combine to produce especially high and low tides, called spring tides. When the Sun and Moon pull at right angles to each other, the difference between high and low water is smaller, and these gentler tides are known as neap tides.
Correct answer A. Around the time of a full moon
The passage says spring tides, with especially high and low water, occur when the Sun, Moon and Earth line up at new moon and full moon, so a full moon brings the greatest difference.
