At night, a flock of crows will generally perch close together in a small place—often a piece of wooded land—called a roost. ████ ████████ ███ █████ █████ ███ █████ ███ ███ ███ ██ █████ ██████ ██ ████ ███ ████████ ███ ███████████ █████ ███ ████ ███████ ███ ██████ ███████ ███████ ██ ███ ██ ███ ██ ███ ██████████ ███ ██ ██ ██████ ████ ███ ██████ █████████ █ █████ ████ ████████ ██ ██████ ███ ████ █████ ███ ███████ ███████████ ██████ ███ ████ ██ ████████ █ █████ ████ ███ █ ███ ████ ███ ███ █████ ██ ███████ ████ ████ █████ ██████████ █████ ██████ █████
Summary
At night, a flock of crows will usually perch in a small place called a roost.
Every morning, the crows leave the roost to hunt and scavenge. Most flocks of crows keep their hunting to within 100 to 130 km from the roost.
Normally a flock of crows stays in the same roost for several years.
When a flock abandons a roost to form a new roost, the new roost is usually less than 8 km away from the abandoned roost.
Notable Valid Inferences
There’s no clear inference from the stimulus. I’d rely on process of elimination to identify which answer can most justifiably be rejected.
