Select the absolute phrase in this sentence.

the baby toddled across the room with his first wobbly steps, his chubby legs pumping.

The correct answer is "his chubby legs pumping"

Explanation:

In sentences, an absolute phrase is a set of words that act as a modifier as they refer to a noun. Besides this, absolute phrases can be identified because they are separated from the main sentence by using a comma and these are not essential to the meaning of the sentence.

In the case of the sentence "The baby toddled across the room with his first wobbly steps, his chubby legs pumping" the section "his chubby legs pumping" acts as an absolute phrase because this describes or modifies "the baby"; also, this is separated using a comma and it is not essential as it can be removed.

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.
