+Given a predicate function, `fn`, and a `prop` string, this curried function will then take an object to inspect by calling the property and passing it to the predicate.
+
+Return a `lambda` function that takes an object and applies the predicate function, `fn` to the specified property.
+
+```py
+def check_prop(fn, prop):
+  return lambda obj: fn(obj[prop])
+```
+
+```py
+check_age = check_prop(lambda x: x >= 18, 'age')
+user = {
+  'name': 'Mark',
+  'age': 18
+}
+
+check_age(user) # True
+```
