<p>Whether the ancient Egyptians actually sailed or did not to South America remains uncertain, but Heyerdahl's Ra II expedition demonstrated that they could have done so.</p>
<p>A) Whether the ancient Egyptians actually sailed or did not
B) Whether in actuality the ancient Egyptians sailed or did not
C) The actuality of the sailing by the ancient Egyptians
D) That the ancient Egyptians actually sailed
E) The ancient Egyptians, their actual sailing</p>
<p>Answer is D, but why? Is it grammatically correct to start off the sentence with "That" ?</p>
<p>In cases like this, rearrange the parts and it will make more sense: "It is uncertain that the ancient Egyptians actually sailed to South America."</p>
<p>It`s D because the other choices look absurd</p>
<p>A)may look fine at first,but the correct grammar rule is '' whether sth happened or not'' ,not ''wheter sth happened or DID not.
B) contains the word 'actuality' - does it sound rightt?
C)again ..
D)correct
E)awkward and wrong</p>
