Question restatement: The question asks whether the statement 'The world’s first vacuum cleaner was developed by Murray Spangler' is true or false. Answer options provided: True; False.
Option 1: True. This would claim that Murray Spangler invented or developed the world’s first vacuum cleaner. In historical terms, while James Murray Spangler did develop an early portable electric vacuum cleaner in 1907, he is not universally recognized as the inventor of the very first vacuum cleaner overall. There were earlier vacuum devices (for example, Daniel Hess in the 1860s) and later developments (such as Booth's electric cleaners in 1901). Therefore labeling Spangler as the inventor of the world's first vacuum cleaner is an oversimplification or inaccuracy, which makes this option incorrect.
Option 2: False. This option contends that Murray Spangler did not develop the world’s first vacuum cleaner. Given the existence of earlier vacuum devices and the fact that Spangler’s contribution was to a portable electric model rather than the absolute first device, this statement aligns more closely with historical nuance. It acknowledges that while Spangler contributed a pivotal design and helped popularize portable vacuums (later associated with Hoover), he did not single-handedly invent the world’s first vacuum cleaner.
Misconceptions and nuances to watch for: Some sources credit Spangler with inventing the first practical portable electric vacuum, which can create confusion about being the 'world’s first' overall. The question’s phrasing is broad (world’s first vacuum cleaner) rather than specifically the first portable electric model, so the broad historical claim is not accurate. This is why the False option is the appropriate choice in this context.
