Final answer:
The best evidence to support the prediction that a Section 8 voucher will not prevent the family from becoming homeless is the average wait time of almost three years for such assistance. Given their urgent need and financial strain, such a delay is a significant barrier.
Step-by-step explanation:
The evidence that best supports the prediction that a Section 8 rental assistance voucher is unlikely to prevent the family from becoming homeless is B. The average wait for a voucher is almost three years. Given the immediate need of the family due to the rent increase and their already strained financial situation, a multi-year wait will not address their urgent need to secure affordable housing. Options A, C, and D mention qualifying criteria and prioritization for specific groups, but they do not inherently mean a family will not receive a voucher, only that there are additional considerations in the allocation process. However, a wait time of several years is a direct and significant barrier to receiving needed assistance promptly.
Matthew Desmond in his book Evicted: Poverty and Profit in the American City underlines that extreme rent burdens leave families vulnerable to homelessness and advocates for a universal housing voucher program as a possible remedy. However, he acknowledges that even with vouchers, affordable housing remains a critical issue. Hence, the combination of a lengthy waiting period and shortage of affordable housing indicates that vouchers alone may not suffice to keep the family in their home.
