Read the following passage: as the new england weather gets colder, we enjoy watching the canada geese as they migrated south for the winter. based on the clues, what is the most likely definition of the word migrate? to swim to move to fly to walk

The correct answer is:  [B]:  "to move" .

Note:  Even though we are taking about "birds" (specifically "Canadian geese") ; which do, in fact, "fly" , we must note the following text:
 
 " As the New England weather gets colder, we enjoy watching...as they migrated south for the winter." .

Base on the verb tenses used, and the specific language:  "As the winter gets colder..." ;  the implication is that "migrate" means:  "to move" ;  since the text implies that this is a seasonal, yet routine occurence—to a different LOCATION.  

Furthermore, other animals migrate (that do not "FLY" — and that are NOT "birds".  

The correct answer is:  Answer choice:  [B]:  "to move" .
