G2 SEC examination questions often contain several constraints at once. A learner may need to use one source, give two reasons, stay within a time interval, report in a stated unit and preserve a condition from the question stem. These constraints form a constraint stack.
This one-hundred-and-twenty-fourth Learner’s Guide develops constraint-stack control across K200 English, K210 Mathematics and K223–K225 Science. It extends Vol 0092 Instruction Hierarchy and Vol 0120 Answer-State Control.
The constraint-stack protocol
List the active constraints before solving: task, source, scope, count, representation, unit, domain and final form. Distinguish hard constraints that must be satisfied from preferences that merely improve clarity. Then check the final answer against the stack from top to bottom.
1. paper-wide instruction
For paper-wide instruction, identify where the constraint originates and how long it remains active. Some constraints are global, some expire at the section boundary, and some apply only to one subpart.
For practice, solve an item while deliberately violating this constraint but keeping the subject knowledge correct. Then repair only the violation. This demonstrates why correctness is not merely having a true fact or accurate calculation; the response must satisfy the live specification.
When two constraints appear to conflict, reread their scope. A local condition may narrow a general rule without cancelling unrelated global requirements. Do not invent an override unless the paper explicitly supplies one.

Hard constraints versus useful preferences
A requested unit, source or number of reasons is a hard constraint. Neat layout or a preferred solving method may be useful but is not equivalent. Under time pressure, satisfy hard constraints before polishing preferences.

Final rule
A strong answer satisfies every active hard constraint at the same time. Keep the stack visible, let local conditions narrow the task where appropriate, and close the answer only when no required constraint remains unpaid.
