Given the question: I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "Currently, the Regular Force component of the Army consists of three field-ready brigade groups: 1 Canadian Mechanized Brigade Group, at CFB Edmonton and CFB Shilo; 2 Canadian Mechanized Brigade Group, at CFB Petawawa and CFB Gagetown; and 5 Canadian Mechanized Brigade Group, at CFB Valcartier and Quebec City. Each contains one regiment each of artillery, armour, and combat engineers, three battalions of infantry (all scaled in the British fashion), one battalion for logistics, a squadron for headquarters/signals, and several smaller support organizations. A tactical helicopter squadron and a field ambulance are co-located with each brigade, but do not form part of the brigade's command structure."?
The answer is:
What is a form of interaction?
