keywords: 

{'primary waves': [0, 0, 0, 2], 'waves': [0, 0, 3, 0], 'earthquakes': [2, 0, 0, 2]}

Option 1: This statement is correct. Primary waves (P-waves) are indeed similar to sound waves as they both propagate through compressional and rarefaction cycles.

Option 2: This statement is the correct answer. Contrary to this statement, primary waves can travel through solid, liquid, and gaseous materials. Unlike secondary waves (S-waves) that cannot propagate through liquids and gases, P-waves can travel through all three states of matter.

Option 3: This statement is correct. P-waves are known to travel through gaseous, liquid, and solid materials. This is one of the characteristics that differentiate them from S-waves.

Option 4: This statement is correct. P-waves are the fastest seismic waves, and they are the first to arrive at the surface during an earthquake. This is due to their ability to travel through all types of materials, allowing them to traverse the Earth`s interior more efficiently.

Therefore, the statement in option 2 is not correct. P-waves can travel through solid, liquid, and gaseous materials.
