The correct answer is letter D: weaker social relationships.
Modernization brings to the world positive and negative sides.
Long life expectancy, establishment of educational institutions and higher rates of literacy can be considered some of the positive sides of modernization.
The technology has been evolving and it brings lots of discoveries that help humans take better care of their health, hence live longer.
Also, a huge concern is education. Modernization brings new technologies on education, new methodologies, and more educational institutions, which leads to the higher rates of literacy, once people who didn't have the opportunity to study before, get to study nowadays.
But modernization brings negative effects, and we can say that it makes social relationships weaker, once people are always using their cellphones and laptops and don't pay attention anymore to the real world. The modern conversations happen through social media, and not face-to-face, which leads to a society where people are always connected to people that are far away, and disconnected from people that are close.
