WGU D265 OBJECTIVE ASSESSMENT 2
— CRITICAL THINKING, REASONING,
AND EVIDENCE
Practice Question Bank | 2026/2027 Study Edition | Detailed Rationales
This study resource provides original, challenging practice questions designed to help you
prepare for WGU D265: Critical Thinking, Reasoning, and Evidence. These are practice
materials, not verified questions from the actual assessment, and no particular grade or passing
result can be guaranteed.
Introduction
Critical thinking is an essential academic skill that enables students to evaluate arguments,
distinguish reliable evidence from unsupported claims, identify assumptions, recognize logical
errors, and make reasoned decisions. WGU D265: Critical Thinking, Reasoning, and Evidence
focuses on developing these skills and applying them to realistic situations involving
information, arguments, and competing conclusions.
This practice question bank is intended for students preparing for the D265 Objective
Assessment who want to strengthen their analytical reasoning and build confidence before taking
the assessment. The questions emphasize application, interpretation, evaluation, and judgment
rather than simple memorization.
Each multiple-choice question includes four answer options, one clearly identified correct
answer, and a detailed rationale explaining why the correct option is strongest and why the
alternatives are less appropriate. Working through the scenarios can help you identify
weaknesses, improve your ability to assess evidence, and develop a systematic approach to
difficult questions.
For the best results, attempt each question before reading its rationale. Review incorrect answers
carefully, identify the reasoning error involved, and revisit concepts you find difficult. Use this
resource alongside your official WGU course materials and assessment guidance.
1. CONTENT AREA OVERVIEW
The following study map organizes the major critical-thinking skills relevant to this practice
bank. Confirm the official competencies and their weighting in your current WGU course
materials; the percentages below are suggested practice allocations, not official assessment
weights.

The questions below are original study exercises. The correct answer is bolded, and each
rationale explains all four options.
Domain 1: Argument Analysis and Structure
Q1. A university administrator argues that the university should extend library hours because
students who studied later during a pilot program reported greater satisfaction. Which additional
information would most directly strengthen the administrator's argument?
A) The library recently purchased new furniture.
B) Usage records show substantial late-night demand, and students who used the extended hours
reported that they could study more effectively.
C) The university cafeteria closes before the library.
D) Several administrators personally prefer studying at night.
Rationale: B is correct because evidence of actual demand and improved study effectiveness
directly supports the claim that extended hours benefit students. A is unrelated to the effect of
library hours. C establishes a separate scheduling fact but does not demonstrate a benefit from
extending the library's hours. D describes administrators' preferences rather than students' needs
or outcomes.
Q2. A manager states, "Our customer complaints fell after we introduced employee training;
therefore, the training caused the reduction." Which assumption is most important to examine?
A) Every employee enjoyed the training.
B) The training materials were expensive.
C) No other significant change adequately explains the reduction in complaints.
D) Customers always submit complaints immediately after a poor experience.
Rationale: C is correct because the argument makes a causal inference from a sequence of
events. Changes in staffing, product quality, customer volume, or complaint procedures could
also explain the reduction. A and B concern employee reactions and cost, neither of which
establishes causation. D makes an overly broad claim about customer behavior and is
unnecessary to the causal argument.
Q3. A researcher concludes that a new teaching method improves learning because students
using it scored higher on a final test. Which question most directly tests the conclusion?
A) Was the teaching method visually appealing?
