To determine which keyword search will retrieve the most results in an online database, you can analyze the specific operators used in each option:
A. "Beta": This keyword search will retrieve results that specifically include the term "Beta."
B. "Beta OR blockers": This search uses the OR operator, which means it will retrieve results that include either "Beta" or "blockers" or both.
C. "Beta NOT blockers": This search uses the NOT operator, which means it will retrieve results that include "Beta" but exclude any results that also contain "blockers."
D. "Beta AND blockers": This search uses the AND operator, which means it will retrieve results that include both "Beta" and "blockers" together in the same result.
Based on these explanations, option B ("Beta OR blockers") is likely to retrieve the most results because it includes two keywords and the OR operator allows for results that contain either one or both of the keywords.
Regarding the question about which option probably contains the most objective data, we can consider the nature of the content in each option:
A. A memoir about working in a coal mine: Memoirs are personal accounts and may be subjective, focusing on personal experiences rather than objective data.
B. A report with charts documenting hourly wage rates by occupational group: This option presents specific data in the form of charts, making it more likely to contain objective information.
C. A letter rebutting an article in a medical journal: Letters often express personal opinions or counterarguments, so this option might lean towards subjectivity rather than objectivity.
D. An editorial in The Washington Post: Editorials are typically opinion pieces, representing the views of the author, which means they tend to be subjective rather than objective.
Based on this analysis, option B (A report with charts documenting hourly wage rates by occupational group) is most likely to contain the most objective data as it presents specific factual information in a structured form.
