In the same manner as two-step questions, USMLE Step 1 conjunction questions require two correct choices to arrive at the best answer. Options are presented as sets of terms or facts linked by a conjunction (usually the word “and”). The best answer is the one in which both parts of the option are correct.
By using this type of question, the examiners are able to move beyond asking for a single piece of information, asking instead which two pieces of information satisfy the question criterion. Most commonly, students are asked to detect two overlapping disease states, or which are the two best interventions to be performed next.
Conjunction Practice Question
The correct answer is A, dominant parietal and frontal lobes.
Strategy for Conjunction Questions
The best method for handling a conjunction question is to treat it as two separate questions. Answer the question twice, once for each part of the response option. Cognitively, it is difficult to hold the two parts of the option in mind at the same time. By splitting the task into two simpler choices, you are less likely to become confused or make mental mistakes. For example, in the previous question, first notice that some of the symptoms are suggestive of a frontal lobe lesion; then as a second step, focus on those that suggest a dominant parietal lobe dysfunction.
