"researcher access to confidential records adds to the vulnerability of workers who participate in workplace studies. inappropriate release of identifiable private information could adversely affect a worker's retention of a job, insurance or other employment related benefits. to avoid or minimize these risks, the study design must include adequate safeguards to protect the confidentiality of the information collected. a plan for the proper management of study data and records should clearly define: "

I believe the answer is:

- Who will have access to the data.

Determine who had the authorization to access the data in order to prevent the risk of alteration.

- If the study results, if any, will be included in the employee's personnel records

So people who use the records in the future could use it as a basis for consideration

- How the data will be collected and secured

They do this in order to differentiate which data would be valid as consideration for the research and which are not.

- If personal identifiers will be retained and used in the data analysis.

the 2nd option is the answer

every society, in order to meet the needs of it's people, has to answer three basic questions:

- what should we produce?

- how should we produce it?

- for whom should we produce it?

this questions must be answered in order to, option b, aid in production decisions.

every country can't produce everything, no matter how rich their land is. it may be a matter of technology, resources or geographical conditions. so, these three questions must be resolved in order to get the most of the production of each land.

hope this !
