'_____ study is limited to single-language repositories written in Python.' What does this sentence accomplish in a limitations section?
'This study is limited to [scope]' is the standard phrase for defining the boundaries of your research. It is not an apology — it is precise scoping. All research has scope limits; declaring them explicitly shows methodological honesty and prevents readers from over-generalising your findings to contexts you did not study.

'_____ work should investigate whether these results generalise to multilingual codebases.' What does this phrase signal?
'Future work should' is the conventional phrase for directing the research community toward open problems your paper has not solved. It signals intellectual honesty (you know your scope) and contributes to the field by identifying research gaps. Other forms: 'Future research could explore', 'Subsequent studies might address', 'A promising direction for future work is'.

'_____ to validity include the reliance on a single proprietary dataset.' What category of research limitation does this phrase introduce?
'Threats to validity' is a formal term from research methodology, distinguishing types of validity at risk: internal validity (did the study correctly isolate the effect?), external validity (do results generalise?), construct validity (does the measure match the concept?), and conclusion validity (are statistical conclusions sound?). Using 'threats to validity' signals familiarity with research methodology discourse.

'The _____ of these findings is restricted to enterprise software teams with over 100 developers.' What word correctly describes the reach or applicability of results?
'Scope of findings' is the standard phrase for describing how broadly the results apply. 'The scope is restricted to X' is more formal and precise than 'limited to' — it implies a deliberate boundary rather than a failure. In limitations sections you might write: 'The scope of this study is restricted to synchronous communication tools; asynchronous tools were excluded by design.'

'We acknowledge that the lack of a control group represents a _____ to the internal validity of this study.' Which word correctly fills the blank?
'Threat to validity' is the technically correct phrase — not 'problem' or 'mistake', which imply avoidable errors. A threat is a methodological constraint that may affect the interpretation of results. Internal validity threats include selection bias, maturation, instrumentation changes, and lack of randomisation. Naming the threat and explaining its likely impact shows methodological sophistication.
