Why do you think the igbo people have so much superstition surrounding ogbanje children? select all that apply

In Igbo language, the literal translation of Ogbanje is "children who come and go". The reasons why the Igbo people of Eastern Nigeria have so much superstition surrounding Ogbanje children are as follows:

1. They do not have any medical or scientific explanations concerning infant mortality. 
2. They believe in reincarnation (life after death).

Photography has changed its subject matter quite a lot over the past few years. in the 1800's, it was considered normal for families to have  post mortem photos of their loved ones, and now that would be completely unacceptable. i think that photographers have always pushed boundaries and have been eager to capture everything, it is just society that changes their boundaries.

Ithink that'd be 4, sorry if i'm wrong.
