According to Table 2.1, crushed rocks of all types are classified by shape as:
A{'text': 'Rounded aggregates', 'label': 'A'}
B{'text': 'Irregular or partly rounded', 'label': 'B'}
C{'text': 'Angular aggregates', 'label': 'C'}
D{'text': 'Flaky aggregates', 'label': 'D'}
Answer & Solution
Correct answer: C. {'text': 'Angular aggregates', 'label': 'C'}
1. Table 2.1 lists: Rounded = river/seashore gravels; Irregular = pit sands and dug flints; Angular = crushed rocks of all types; Flaky = laminated rocks.
2. So crushed rock fits in the Angular row.
