　　3.      x

　　Explanation

　　See the first two sentences in Section C “The cells detect subtle water movements， and from the different times that the individual cells are stimulated by these movements the fish's brain is able to reconstruct an image of what caused them in the first place.”。

　　4.      iii

　　Explanation

　　See the first two sentences in Section D“Dr Liu's artificial lateral line was somewhat shorter than a natural one…The sensors themselves contained heated filaments and worked by recording how quickly the heat was lost”。

　　Explanation

　　See the first sentence in each paragrph of Section G“Artificial lateral lines would have many applications. Dr Liu also speculates about using lateral lines to detect air-movements”。

　　12.  TRUE

　　Explanation

　　See the last two sentences in Section G “A lateral-line system could. The vortices thrown off by water moving past even a stationary object would be visible to it.”

　　13 .C

　　Explanation

　　See the fourth sentence in Section D “The faster that water moved past a filament， the quicker the filament lost heat.”

　　14    D

　　Explanation See the last two sentences in the first paragraph of Section E “A lateral-line system could. The vortices thrown off by water moving past even a stationary object would be visible to it.”
