Explanation:
Jack Riis is a American newspaper reporter, social reformer and photographer.
<em><u>These tenements were for poor immigrants that just came to the United States to start a better life. These tenements were overcrowded, unsanitary, and unsafe housing. At least 18 people lived in one tenement apartment. There were only two toilets stalled on each floor and one bathtub in the kitchen of the apartment. Jacob Riis did a lot of research and reporting of the conditions that immigrants faced such as work issues and living conditions. He wanted to improve the living conditions that these individuals had and address working issues.He possessed great deals of energy which is why he was able to expose as much as he did about the slums. Jacob Riis crusaded for the establishment of settlement houses, public parks and playgrounds, and other reforms to improve the lives of those in New York City's slums.</u></em>

Answer:
Hands off policy would be described as the policy that means not intervening in matters.
If a president has announced an off hands policy in some matter, that means he has declared that he will not intervene in that matter under any circumstance. He would have nothing to do with it and nobody shall try to have him indulged in that matter.
I hope the answer was helpful.
