If the elevation above water level of a breaching whale is given by the expression 

−t2+12t−35

 where 

t

 is the time, in seconds, after an observer begins watching, is the whale presently underwater? 

1) 

t<8



2) 

t>5

.

Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient to answer the question asked

Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer the question asked

Both statements (1) and (2) TOGETHER are sufficient to answer the question asked; but NEITHER statement ALONE is sufficient

EACH statement ALONE is sufficient to answer the question asked

Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data specific to the problem are needed
