D.the sentence is correct as it is written
Virtual learning was a modality that most students, until then, did not know. However, the moment in which we are living and the need for social distancing made virtual learning not just a necessity, but the only type of teaching allowed.
Although it may seem like a promising system, virtual learning has raised questions that are likely to shape the future of schools and education not only in the country, but worldwide. It is now questionable whether virtual learning is really effective and whether it will be able to prepare students for higher academic and professional levels. This is because it distances the student from the teacher, decreasing the ability to exclude doubts from them, in addition to being a type of learning that is constantly susceptible to distractions, since it is not carried out in an environment suitable for this. In addition, not all the population that needs to study has access to the devices needed for virtual learning. We must not forget that this type of service makes the teaching service more expensive, since it guarantees an even greater workload.
With this, we can say that virtual learning promotes a higher expenditure on education in exchange for a less qualified education and therefore should not be adopted as a substitute for traditional education in the future. However, we know that virtual learning has some advantages, which may justify its fusion with conventional learning in some factors, as long as this allows education in a country to be more inclusive, efficient and egalitarian.
May you show us the passage?...
During the World War II era, the United States military struggled to find enough able-bodied men to fly the military aircraft. General Henry “Hap” Arnold teamed up with Jacqueline “Jackie” Cochran to create a task force of female pilots to help in the fight against the Axis Powers. The U.S. Air Force had difficulties finding a solution to their conflict: they needed women to fly aircraft on the homeland, but at the time women were prevented from being in the military. The Air Force finally compromised by allowing women to perform only noncombat jobs. Originally, the women were separated into two groups: the Women’s Auxiliary Ferrying Squadron (WAFS) and the Women’s Flying Training Detachment (WFTD). Later these groups would combine into the group known as the Women Airforce Service Pilots (WASPs). The hard work and perseverance of the WASPs led to the 2015 ruling allowing women into all military positions. Though they encountered much opposition, the WASPs proved that females deserve to be seen as equal to men.
Pretty Sure It's An Opinion. That fact Can Be Debated.
