ok Clarity
The question is clearly phrased, identifying a specific individual and a specific historical event. It is unambiguous in what it is asking.

ok Relevance
The question addresses a well-known historical event and a commonly debated contributing factor, making it relevant within its domain of inquiry (e.g., cultural history, musicology).

minor Feasibility
Investigating historical causality is inherently challenging, as complex events rarely have a single, isolated cause. However, a study could plausibly be designed using historical research methods, including analysis of primary sources (e.g., interviews, memoirs, contemporary reports) and secondary literature. The difficulty lies in definitively isolating a single cause for a complex event, but this does not render the study impossible to design.

ok Falsifiability
The question is falsifiable. Evidence could be gathered (e.g., testimonies from band members, historical records, analyses of band dynamics pre- and post-Yoko Ono's increased involvement) that either supports or refutes the causal link, or demonstrates other factors were more significant.

Implicit assumptions

• The question assumes that the breakup of The Beatles had a singular or primary cause that can be attributed to one individual. Complex historical events often have multiple, interacting contributing factors.
• It assumes 'Yoko Ono' can be treated as a singular causal agent, rather than her interactions with band members or the band members' reactions to her being part of a broader dynamic.

Missing information (formulation stage)

• Definition of 'cause' in this context — To guide the scope of evidence collection and the criteria for establishing the causal link (e.g., was she a necessary condition, a sufficient condition, a primary driver, or a contributing factor?).
• Specific timeframe for 'breakup' — While generally understood, defining the exact period of the 'breakup' process (e.g., from initial tensions to public announcement) would help delineate the period during which causal factors would be investigated.

Revision suggestions

• Consider reframing the question to explore the *extent* or *nature* of Yoko Ono's influence on the Beatles' breakup, rather than seeking a singular causal attribution. This would better reflect the complexity of historical events and allow for a more nuanced investigation.

Design-stage notes (non-blocking)

• Define specific criteria for what constitutes 'causing' the breakup (e.g., direct actions, indirect influence, exacerbation of existing tensions, impact on band dynamics).
• Identify and categorize primary sources (e.g., interviews with band members, associates, contemporary media reports, personal diaries, official documents) and secondary sources (e.g., biographies, academic analyses) to be analyzed.
• Establish a methodology for analyzing qualitative data from historical sources to identify themes, patterns, and potential causal links (e.g., content analysis, thematic analysis, narrative analysis).
• Consider the use of counterfactual analysis to explore what might have happened if Yoko Ono had not been involved, acknowledging its inherent limitations in historical research.
• Specify the scope of 'the Beatles' breakup' (e.g., the decision to disband, the cessation of recording/touring, the public announcement, the legal dissolution of the partnership).

Declared uncertainty
I cannot assess the specific historical evidence available or the researcher's access to it, which would impact the depth and richness of the feasibility assessment and the potential for a comprehensive answer.
