Answer 1

(1) (2) (3) (4)

Explanation: 

1. "The alternate advance and retreat of seawater along a coast is called tide."
   True – This describes the basic definition of tides, which are periodic rises and falls of sea level due to the gravitational pull of the Moon and the Sun.

2. "When water advances to its fullest extent on to the shore it is called high tide."
   True – High tide is the point at which the sea has risen to its maximum level on the shore.

3. "When water recedes to its fullest extent from the shore it is called low tide."
   True – Low tide is when the sea level is at its lowest, having moved away from the shore.

4. "Some freshwater rivers and lakes can have tides too."
   True – Although tides are most noticeable in oceans, some large rivers and lakes near coastal regions (like the Amazon River or Bay of Fundy) can experience tidal effects due to their connection with tidal seas.
