What do pull strategies involve in the context of information gathering?

Pull strategies in information gathering are primarily characterized by obtaining information directly from a source, often through methods such as direct communication with experts or accessing detailed insights from primary sources. This approach emphasizes the proactive retrieval of data based on specific needs or inquiries, allowing for tailored and relevant information to be received.

In this context, receiving information directly from an expert exemplifies the reliance on specialized knowledge and experience, ensuring that the gathered information is accurate, current, and applicable to the situation at hand. Experts can provide deep insights that may not be readily available in secondary resources or databases, making this method particularly valuable for complex or nuanced topics.

The other choices address concepts related to information gathering but do not entirely reflect the essence of pull strategies. Extracting information from online databases and acquiring information from sock resources are more aligned with push strategies, where data is gathered from existing repositories instead of being tailored to specific inquiries. Manipulating data for user benefit implies a focus on how information is used rather than the method of gathering it, which diverges from the principle of pulling information directly in an interactive and responsive manner.
