In addition to housing shortages, what type of "poor conditions" did
migrants face?

See explanation

Explanation:

You didn't give the options and I couldn't find a particular question relating to your question but let me help out.

Some of the challenges that migrants face include:

• Housing challenges: Finding a home can be tough for migrants. Based on the fact that they are new and don't know much about the housing market, thus may tend to be a problem.

• Language barriers: One of the most important thing when one moves to a new environment is the language which will be used in communication.

Migrants move to another country so as to better their life and language can be a barrier when they eventually get to such countries.

• Employment opportunities: Another issue is with regards to employment. Migrants may realise that it hard to get suitable jobs.

• Access to local services: Immigrants also face difficulties in accessing the local service such as social services, health care, and legal advice.

• Cultural differences: This can also be a problem as immigrants face cultural difference especially when they are moving to a place where their culture is totally different from theirs.

i really really really really really really dont know

the underground railroad (apocope of the metropolitan railroad) is a system of urban trains located within a city and its metropolitan area. it is characterized for being a massive transport of passengers in the big cities, uniting diverse zones and their environs, with high capacity and frequency and in segregated form to other systems of transport. metropolitan railroads are built underground or on the surface, although most systems use mixed models where sections are combined in both modalities.

1 - as a result, the metro tends to reduce car travel for two reasons: first, due to the greater transfer of users from the car and, second, due to the reduction in the acquisition of cars in homes located in sectors near the stations of the metro.

2 -the metro allows to contribute effectively to the achievement of all the objectives of an urban development policy: it improves the efficiency of the city's economy by reducing travel costs and also generates a higher level of activities in the city center, taking advantage of of the agglomeration economies.

3 -it is a clean means of transport, since it uses renewable energy (usually electricity), taking care of the environment and avoiding excessive pollution.
