Question
Difficulty: hard. Skill: analyze. Type: applied scenario.
During teaching, a student responds correctly with one example but errors increase with new materials and staff. Across 8 sessions in service week 8, 2 observers recorded 44 minutes of observation in the elementary classroom. The BCBA should:
ADeliver the same consequence for the target response and the replacement response.
BTrain only one example and wait to see whether transfer happens naturally.
CKeep the most intrusive prompt in place so errors stay low during teaching sessions.
DPair instructions or modeling with rehearsal and consequences that show the response contacts the relevant contingency.Correct answer

Explanation
Answer DThe decision point is: Does the answer match the teaching or behavior-change procedure to the function, skill, and stimulus-control problem? This item specifically tests Instructions and rules through a applied-client-service-scenario format. The key clue is in the stem facts: During teaching, a student responds correctly with one example but errors increase with new materials and staff. Across 8 sessions in service week 8, 2 observers recorded 44 minutes of observation in the elementary classroom. The BCBA should: Answer D is strongest because it follows this rule: Pair instructions or modeling with rehearsal and consequences that show the response contacts the relevant contingency. It fits the source-backed rule without announcing that rule in the stem. The tempting mistake is to choose a shortcut before the scenario's prerequisite is satisfied. This choice treats a procedure or response form as enough. The scenario still requires matching the action to function, assessment results, or the decision rule. Exam move: name the missing prerequisite first, then eliminate answers that jump to a label, a familiar procedure, a single data point, or an undocumented action.

Why the other choices are weaker
AChoice AThis choice treats a procedure or response form as enough. The scenario still requires matching the action to function, assessment results, or the decision rule.
BChoice BThis choice overgeneralizes from limited evidence. The stronger answer checks the controlling variables before assuming the same relation holds elsewhere.
CChoice CThis choice moves too quickly toward a more intrusive response. The better answer checks function, risk, feasibility, and less intrusive options first.
