Do you think the growth of the railroads in Texas will have advantages or
disadvantages for future Texas? Why?

in my opinion it will have disadvantages and advantages because workers life might change because workers will have to pay wages and some people will lose their jobs due to faster machines and some advantages are that it will be faster transportation and will give unmarried women and men the chance to make their own money.

the andes or andean mountains (spanish: cordillera de los andes) are the longest continental mountain range in the world, forming a continuous highland along the western edge of south america. this range is about 7,000 km (4,300 mi) long, about 200 to 700 km (120 to 430 mi) wide (widest between 18° south and 20° south latitude), and of an average height of about 4,000 m (13,000 ft). the andes extend from north to south through seven south american countries: venezuela, colombia, ecuador, peru, bolivia, chile and argentina.
