1Which best describes 'algorithmic bias' as discussed in the CET-110 blueprint?
A.A defect in compiler optimization that slows model inference
B.Systematic errors in an algorithm's outputs that create unfair outcomes for specific groups
C.A network bandwidth limitation in distributed training
D.A statistical artifact that affects only synthetic data
Explanation: Algorithmic bias is the systematic and repeatable production of unfair outcomes by an algorithm — outcomes that disadvantage particular individuals or groups. It can stem from biased training data, biased proxies, biased labels, or biased optimization objectives.
2A team is asked to identify which ethical theory judges actions by their consequences and aims to maximize aggregate well-being. Which theory is being described?
A.Deontology
B.Virtue ethics
C.Consequentialism (utilitarianism)
D.Contractualism
Explanation: Consequentialism evaluates actions by their outcomes; utilitarianism (Bentham, Mill) is the dominant variant, advocating actions that maximize overall well-being or utility. CET-110 expects candidates to recognize the major moral-philosophy traditions.
3Kantian deontology is best summarized as the view that:
A.Only outcomes matter; intentions are irrelevant
B.Acts have intrinsic moral status determined by duty and universalizable maxims
C.Moral truth is whatever the most powerful group decides
D.All ethics reduces to economic incentives
Explanation: Kantian deontology holds that the morality of an action is determined by whether it conforms to a moral rule (maxim) one could will as a universal law, and by respect for persons as ends in themselves. The categorical imperative is its central test.
4Aristotle's virtue ethics emphasizes:
A.Maximizing aggregate utility across society
B.Cultivating stable character traits (virtues) that enable human flourishing (eudaimonia)
C.Strict obedience to a written legal code
D.The rejection of all ethical claims as subjective
Explanation: Virtue ethics centers on the moral agent's character — virtues such as courage, justice, prudence, and temperance — and on living a flourishing life (eudaimonia). It contrasts with rule-based deontology and outcome-based utilitarianism.
5Which scenario is most appropriate for triggering an Ethics-by-Design review at the IDEATION stage?
A.After a customer complaint forces a recall of a deployed model
B.When a product team is brainstorming a new use case for facial recognition in retail
C.Only when regulators demand a written response
D.Only after a system has been live for one full year
Explanation: Ethics-by-Design and 'what-if' reviews belong at the earliest stages — ideation and concept exploration — where ethical risks can be designed out at low cost. CET-110 specifically lists ideation and new-product reviews as triggers for ethical risk assessment.
6Which evaluation metric measures the proportion of true positives among all actual positives?
A.Precision
B.Recall (sensitivity, true positive rate)
C.Specificity
D.F1 score
Explanation: Recall = TP / (TP + FN). It measures how many of the actual positives the model successfully identified. Recall is critical when missing a positive is costly, such as in disease screening or fraud detection.
7Selection bias in a training dataset most commonly arises when:
A.Data is collected in a way that systematically excludes or under-represents some groups
B.A model is trained for too many epochs
C.Hyperparameters are tuned on the test set
D.The model uses too few features
Explanation: Selection bias occurs when the process of choosing data points produces a sample that does not represent the target population — for example, recruiting subjects only from one geography or platform. It distorts every downstream metric.
8An operator notices that human reviewers nearly always agree with the model's recommendation even when it appears wrong. This is BEST described as:
A.Confirmation bias
B.Automation bias
C.Selection bias
D.Aggregation bias
Explanation: Automation bias is the tendency of human operators to over-trust automated recommendations and discount disconfirming evidence. It is a well-documented risk in clinical decision support, autopilot, and triage systems.
9Which ethics term refers to the practice of publicly claiming high ethical standards while not actually operationalizing them?
A.Ethics-by-Design
B.Ethics washing
C.Privacy by Default
D.Algorithmic accountability
Explanation: Ethics washing is the marketing or public-relations practice of branding an organization as ethical without substantive policy, governance, training, or measurable outcomes. CET-110 lists ethics-vs-business conflicts including ethics washing.
10In the context of CET-110, 'applied ethics' is BEST described as:
A.Pure metaethical theorizing about the meaning of moral terms
B.The use of ethical theory to address concrete questions in fields such as AI, biotech, and IoT
C.Compliance with a single national legal code
D.An informal personal philosophy
Explanation: Applied ethics extracts decision-relevant guidance from moral theory and applies it to domain-specific questions — for example, autonomous-vehicle dilemmas, medical AI, or surveillance technology. It is the practical layer between theory and policy.
