PROBLEM: He's being manipulated totally by Fidel Castro. He's not (telling) the truth.
Verb: telling

SOLUTION: Yes

PROBLEM: But the Immigration and Naturalization Service's decision to deny Elian an asylum hearing was within the outside border of reasonable choices, the opinion read. The court neither (approves) nor disapproves the INS' decision to reject the asylum applications filed on plaintiff's behalf, but the INS decision did not contradict ( federal law. )
Verb: approves

SOLUTION: Yes

PROBLEM: If only his father, who is under the control of the Fidel Castro regime, can do it for him... that is deeply unfair and untrue. Meissner (gave) no reason for the Jan. 14 deadline, and it is still unclear how Elian would be transported back to Cuba if the Gonzalez family's appeals are unsuccessful.
Verb: gave

SOLUTION:
Yes
