In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: Freedom from Want was published with an essay by Carlos Bulosan as part of the Four Freedoms series. Bulosan's essay spoke on behalf of those enduring domestic socioeconomic hardships rather than sociopolitical hardships abroad, and it thrust him into prominence. As he neared his thirtieth birthday, the Philippine immigrant and labor organizer Bulosan was experiencing a life that was not consistent with the theme Rockwell depicted in his version of Freedom From Want. Unknown as a writer, he was subsisting as a migrant laborer working intermittent jobs. Post editors tracked down the impoverished immigrant to request an essay contribution. Bulosan rose to prominence during World War II when the Commonwealth of the Philippines, a United States territory, was occupied by Japan. To many Americans, Bulosan's essay marked his introduction, and his name was thereafter well recognized. The essay was lost by The Post, and Bulosan, who had no carbon copy, had to track down the only draft of the essay at a bar in Tacoma.Freedom From Want had previously been less entwined in the standard liberalism philosophies of the western world than the other three freedoms (speech, fear, and religion); this freedom added economic liberty as a societal aspiration. In his essay, Bulosan treats negative liberties as positive liberties by suggesting that Americans be "given equal opportunity to serve themselves and each other according to their needs and abilities", an echo of Karl Marx's "from each according to his abilities, to each according to his needs".  In the final paragraph of the essay, the phrase "The America we hope to see is not merely a physical but also a spiritual and intellectual world" describes an egalitarian America.  In a voice likened to Steinbeck's in works such as The Grapes of Wrath, Bulosan's essay spoke up for those who struggled to survive in the capitalist democracy and was regarded as "haunting and sharp" against the backdrop of Rockwell's feast of plenty. It proposed that while citizens had obligations to the state, the state had an obligation to provide a basic level of subsistence. Unlike Roosevelt, Bulosan presented the case that the New Deal had not already granted freedom from want as it did not guarantee Americans the essentials of life.
What is the first name of the person whose essay spoke on behalf of those enduring domestic socioeconomic hardships?
