Read this section of Uriel’s report about flightless birds. Flightless birds are birds that cannot fly. Scientists do not agree on whether the ancestors of these birds could fly. However, most experts understand that flightless birds are missing body parts that allow other birds to fly.

What should Uriel do to help his readers understand the text, and why?

A.
Set the terms flightless and
ancestors in boldface text so readers understand that these are key words that they should look up.
B.
Create a timeline showing when the ancestors of flightless birds became extinct so readers will understand when birds became flightless.
C.
Add a map showing the location of flightless birds in the world so readers understand the connection between flightlessness and country of origin.
D.
Include labeled illustrations of a flightless bird and a flying bird so readers understand which parts the flightless bird is missing that would allow it to fly.

D.

Explanation:

Uriel, in his article, should include a labeled illustration of a flightless bird and a flying bird, showing the missing body part in the flightless bird.

As the writer in his article has reported that flightless birds are not able to fly because they have some missing body parts that enables a bird to fly. So, showing a labeled diagram of that body part will help the readers to understand the text more clearly.

Therefore, option D is correct.

the speech this question is referring to is president kennedy's special message to the congress on urgent national needs, may 25, 1961

kennedy responds in a very direct and concrete way to those thinking that communism is a positive system:

"yet their aggression is more often concealed than open. they have fired no missiles; and their troops are seldom seen. they send arms, agitators, aid, technicians and propaganda to every troubled area. but where fighting is required, it is usually done by others--by guerrillas striking at night, by assassins striking alone--assassins who have taken the lives of four thousand civil officers in the last twelve months in vietnam alone--by subversives and saboteurs and insurrectionists, who in some cases control whole areas inside of independent nations." (kennedy)

president kennedy presents communism as cowardly, as a hidden and treacherous weapon that strikes from the shadows like thieves, he represents the system as not even being capable of showing and open and overt attack or confrontation. to finish up the response, he expresses that the system attacks even a country's idependence and freedom.

most likely you should find things like facts and important information to you understand. i hope this .
