Why the other options are wrong:

• options for reading glasses.: Reading glasses are unrelated to the report on automation and employment.
• how automated cars are tested.: Testing automated cars is not discussed; the report examines workplace tasks and employment.
• how robots explore Mars.: Robots exploring Mars are not discussed; the examples concern restaurants, factories and classrooms.

Correct Answer: slower and error-prone human labor.

Why this is correct: The report identifies slower and error-prone human labour as the work that more efficient robots and software could potentially replace. It does not claim that every kind of human work can be automated.

Why the other options are wrong:

• all human jobs without exception.: Some tasks remain hard to automate, so replacement of all jobs without exception is too absolute.
• fast and accurate human labour.: The replacement claim names slower and error-prone labour, not fast and accurate labour.
• technical teams alone.: The report does not limit possible replacement to technical teams alone.

Correct Answer: corporate profits.

Why this is correct: The report connects rising automation with more efficient work and says it could support corporate profits in the coming years. Corporate profits is the specific outcome in that statement.

Why the other options are wrong:

• scientists.: Scientists are not named as the beneficiaries of this financial effect. The statement concerns corporate profits.
• future jobs.: The cited claim concerns profits, not a promise that automation will support future jobs. The report treats job outcomes separately.
• new enterprises.: New enterprises are not the stated result. The passage refers to the profits of corporations.

Correct Answer: can be easily automated by robots.

Why this is correct: The report says physical labour in predictable environments could easily be automated with robots and software already available.

Why the other options are wrong:

• are hard to automate with present technology.: The report calls these tasks easy to automate; chaotic physical work is among the harder examples.
• will require technology that does not yet exist.: Present technology is described as sufficient for these tasks, not technology that does not yet exist.
• cannot be automated at all.: Cannot be automated contradicts the explicit easy-automation claim.

Correct Answer: does not necessarily mean that jobs will completely vanish.

Why this is correct: The report says increased technology use does not necessarily make whole jobs disappear. Humans may shift to responsibilities they are uniquely good at.

Why the other options are wrong:

• necessarily makes all jobs disappear.: This reverses the report's qualification: whole jobs do not necessarily vanish.
• only affects businesses founded recently.: The report does not restrict automation's effects to recently founded businesses.
• leaves human workers with no tasks.: Humans may take different responsibilities; the report does not say they have no tasks left.
