Answer:
The two groups of people Ismael faces danger from were the group of muscular men with machetes and crowded village where they stopped on their way.
Explanation:
'A Long Way Gone' is a memoir of Ishmael Beah, a boy soldier during the civil war in Sierra Leone.
In Chapter 8, after roaming around in the forest all alone and encountering with many wild animals, Ishmael was able to come in contact with a group of six children, who like Ishmael were in search of a way out. For Ishmael, the group of these six children were problem because he got accustomed to living all alone. He felt little edgy being around them.
The group of people who were threat to Ishmael were the muscular men with machetes. They were carrying sharp machetes in their hands and Ishmael was afraid and thought how much pain it will cause to be beheaded by machetes. The other group who were threat to Ishmael was the crowded villages where the group of these seven children stopped at. These villagers were so suspicious of these children that they kept their eyes on them, even in night.
