During which years did the job opportunities for Deaf individuals significantly increase due to World War I?

The option indicating the years from 1910 to 1950 is correct because during this period, particularly around and after World War I, there was a significant shift in job opportunities for Deaf individuals. The war effort led to an increased demand for workers in various sectors, as many hearing individuals were drafted into military service. This created gaps in the workforce, and industries began to recognize the potential of employing Deaf individuals, particularly in manufacturing and other areas where communication could be adapted.

Additionally, organizations and companies started to advocate for the inclusion of Deaf workers during this time, which contributed to a gradual acceptance of vocational training and education tailored for Deaf individuals. This period laid groundwork that would lead to more systemic changes in employment opportunities for Deaf individuals, leading up to the mid-20th century.

The other time frames do not encompass the significant changes initiated by World War I and the subsequent societal shifts that directly influenced job opportunities for Deaf individuals. The earlier period up to 1910 did not experience the same level of recognition or employment opportunities, while the latter periods reflected different social dynamics that were not initiated by the same wartime conditions.
