Explanation:

These questions seem to be related to a historical documentary or lesson about American history (specifically Episode 7). Since they are about historical events, figures, and developments, the relevant subfield under Social Science would be History. To answer these, one would need to recall or research information from the corresponding episode or historical sources. For example, for question 1: The gift that needed assembly was the Statue of Liberty (it was a gift from France to the US and needed to be assembled in the US). For question 2: Joseph Pulitzer gathered money (through a newspaper campaign) to assemble the Statue of Liberty's pedestal. For question 3: The Statue of Liberty's face is modeled after the sculptor's mother (Bartholdi's mother) or sometimes said to be inspired by a combination, but commonly the sculptor Frédéric Auguste Bartholdi modeled the face after his mother. And so on for each question, using historical knowledge or the content of the episode.

If we take question 1:

The gift needing assembly was the Statue of Liberty, a gift from France to the US. It was shipped in parts and required assembly in New York.

Joseph Pulitzer, through his newspaper (New York World), ran a campaign to raise funds for the Statue of Liberty's pedestal assembly.

The Statue of Liberty’s face was modeled after Frédéric Auguste Bartholdi’s (the sculptor) mother, Charlotte Bartholdi.

Answer:

The gift that needed assembly was the Statue of Liberty.

For question 2:
