Question

how can this be? it might seem a sure thing that automating a task would reduce employment in an occupation. but that logic ignores some basic economics: automation reduces the cost of a product or service, and lower prices tend to attract more customers. software made it cheaper and faster to trawl through legal documents, so law firms searched more documents and judges allowed more and more expansive discovery requests. likewise, atms made it cheaper to operate bank branches, so banks dramatically increased their number of offices. so when demand increases enough in response to lower prices, employment goes up with automation, not down. and this is what has been happening with computer automation overall during the last three decades. its also what happened during the industrial revolution when automation in textiles, steelmaking, and a whole range of other industries led to a major increase in manufacturing jobs.
but not all of the news about computer automation is good. some of that growth in computer - using occupations has come at the expense of other occupations. as depicted in the chart below, desktop publishing systems have meant fewer jobs for typographers, as graphic designers took over their work. computerized phone lines meant fewer jobs for telephone operators, but more jobs for receptionists. these arent examples of computers “stealing” jobs; they are cases where computers helped some workers take work from others. workers with computers frequently substitute for workers in non - computerized jobs.
typographers: people who set words into type.
analyze graphic features
annotate: mark the sentence in paragraph 7 that connects to the information in the graph.
analyze: how does this graphic feature work with the text to emphasize a key point about computer automation?

Explanation:

The text discusses the impact of computer - automation on employment, with the graph showing the contrasting trends of graphic design jobs increasing and typographer jobs decreasing. The graphic feature visually reinforces the text's point that computer - automation has led to job - displacement in some occupations while creating growth in others. For the annotation part, a relevant sentence in paragraph 7 could be "As depicted in the chart below, desktop publishing systems have meant fewer jobs for typographers, as graphic designers took over their work."

Answer:

Annotation: A possible sentence in paragraph 7 is "As depicted in the chart below, desktop publishing systems have meant fewer jobs for typographers, as graphic designers took over their work."
Analysis: The graph visually represents the text's claim that computer - automation has led to a shift in employment, with graphic design jobs growing and typographer jobs declining, emphasizing that automation causes job - displacement in some areas while creating new opportunities in others.
