Mixed Deck — All CGL Topics Flashcards

Which element is required in a Proof Summary but NOT required in a Proof Argument?

Answer: A title and identification of the research question

A Proof Summary is a standalone, titled document that identifies the research question and presents the conclusion, while a Proof Argument may be embedded in a narrative without a formal title block.

A projector used in a genealogy lecture presentation suddenly displays a color cast with a strong yellow tint. What is the most likely cause?

Answer: The projector lamp is nearing end-of-life

Aging projector lamps shift toward yellow as the mercury vapor depletes, indicating the lamp needs replacement.

Why is staying current with industry developments important for CGL professionals?

Answer: The field evolves and practitioners must adapt to provide quality service

Fields continuously evolve with new research, technology, and best practices that affect professional competency.

A genealogist's laptop battery drains much faster than when new during research trips. Which maintenance action is most appropriate?

Answer: Calibrate or replace the battery and adjust power management settings

Battery calibration can restore accurate charge reporting, but significant capacity loss typically requires battery replacement.

How does 'reasonably exhaustive' differ from 'absolutely exhaustive' in GPS terminology?

Answer: Reasonably exhaustive reflects what a competent genealogist would do given available resources; absolutely exhaustive is an impossible standard

The GPS uses 'reasonably exhaustive' because no researcher can consult every record ever created; the standard is professional competence, not perfection.

A CGL lecturer is presenting to a mixed audience of beginners and advanced genealogists. What is the best approach?

Answer: Layer content by starting with foundational concepts, then adding depth that rewards advanced participants

Layered content respects all experience levels — beginners build a foundation while advanced attendees gain deeper insight from the same material.

Under professional standards, how should a CGL handle personally identifiable information (PII) about living individuals mentioned in lecture examples?

Answer: Anonymize or obtain consent before including PII about living individuals

Protecting the privacy of living individuals by anonymizing or obtaining consent is an ethical obligation for genealogical educators.

When should a scatter plot be used?

Answer: To examine the relationship between two continuous variables

Scatter plots reveal relationships, patterns, and correlations between two continuous variables.

How should equipment calibration records be maintained?

Answer: Documented with dates, results, and next calibration due date

Proper calibration records provide traceability and help ensure equipment continues to provide accurate measurements.

A document scanner's ADF (Automatic Document Feeder) repeatedly misfeeds fragile 19th-century newspaper clippings. What is the safest corrective action?

Answer: Switch to flatbed scanning with manual feed

Fragile documents should always be scanned on the flatbed to avoid mechanical stress from the ADF rollers.

A passenger arriving in New York in 1912 would most likely appear in records maintained under which immigration law?

Answer: The Immigration Act of 1907 and its implementing regulations

The Immigration Act of 1907 and subsequent regulatory changes shaped the detailed manifest forms (Form 500) used in the early 1910s, greatly expanding the information collected.

Which file format is preferred when saving scanned genealogical images for long-term archival purposes to avoid lossy compression artifacts?

Answer: TIFF (.tif)

TIFF supports lossless compression, preserving all image data without the quality degradation caused by JPEG's lossy algorithm.

What is the primary benefit of consistently citing sources during lectures?

Answer: It reinforces credibility and traceability

Consistently citing sources during lectures is crucial for reinforcing credibility and traceability. It demonstrates that the information presented is well-researched and verifiable, allowing the audience to trust the lecturer's expertise. Furthermore, proper citation enables attendees to explore the sources themselves, deepening their understanding and facilitating their own research.

What is the purpose of performing a test scan and histogram review before beginning a bulk genealogical digitization session?

Answer: To verify exposure, contrast, and color settings produce optimal output before committing to a large batch

A test scan with histogram analysis confirms that settings capture full tonal range without clipping highlights or shadows before processing hundreds of documents.

When a CGL receives a negative evaluation from a presentation attendee, what is the most constructive professional response?

Answer: Reflect on the feedback objectively and consider how it could improve future presentations

Objectively analyzing negative feedback, even when uncomfortable, is essential for continuous professional improvement.

Which of the following describes the 'Soundex' system used to index certain U.S. census records?

Answer: A phonetic coding system that groups surnames by their consonant sounds to find name variants

Soundex encodes surnames by their initial letter followed by three digits representing key consonants, grouping phonetically similar names so researchers can find spelling variants.

Why is root cause analysis important in quality improvement?

Answer: It identifies the underlying cause of problems rather than just symptoms

Root cause analysis goes beyond surface-level symptoms to identify fundamental causes, enabling effective and lasting solutions.

How should a CGL lecturer adapt their vocabulary when presenting the same genealogical methodology content to a beginner versus an advanced audience?

Answer: Use plain language and define technical terms for beginners; use professional genealogical terminology freely with advanced audiences

Adapting vocabulary to audience expertise is a core adult learning principle — it prevents alienating beginners while respecting advanced practitioners.

What is the benefit of using census records in genealogy?

Answer: They list family members and relationships

Census records are incredibly beneficial in genealogy because they list family members and their relationships within a household at a specific point in time. These records often include names, ages, birthplaces, occupations, and relationships to the head of the household. This detailed information provides invaluable snapshots of family units, helps track their movements over decades, and can reveal previously unknown family connections.

Land records in which U.S. state were recorded in the Spanish vara land measurement system, reflecting its colonial history?

Answer: All of the above

Texas, Louisiana, and Florida all used the vara (a Spanish linear unit) in colonial-era and early statehood land surveys, reflecting their Spanish colonial heritage.
