下線部(A)の内容を60字以内で説明しなさいと言う設問なのですが、大まかな意味はこれで合ってるでしょうか?💦

解答欄にマークしなさい。 問 2, 間 3, 4, 問5の解答は, 解答用紙 守谷市祗1枚目 (マークシー 2枚目 (記述式) に記入しなさい。 Technology is rapidly and fundamentally changing the way most people do their jobs, disrupting (1) the nature of work and increasing the demand for new kinds of digital skills. The impact can be felt in all kinds of jobs. Gone are the days of copywriters (2) simply writing copy, for instance. Now they also need to be familiar with search engines and social media to know what will make their work more visible online. Architects need to be able to create digital concepts as their clients now often expect to see more than a 2D drawing. Accountants have to keep up with rapid digital advances disrupting their industry such as the growth of online filing. (3) Byron Nicolaides, CEO of PeopleCert, a professional skills assessment and certification business, says: "The digital skill gap describes the effect that has resulted from a shift. towards digitalisation, with the emergence of new professions, alongside the displacement of other roles, that now require continued digital training." Demand for people with high-level digital skills is greater than the supply of suitably qualified employees, and the gap is growing. The World Economic Forum estimates that by 2022 emerging technologies will generate 133 million new jobs in place of the 75 million that will be displaced. "If the demand for digital expertise is not able to be met by the supply, the resulting deficit in a skilled workplace will not only affect the ability of businesses to shape their own future, but will hinder the economic growth and generate a new reality of [digital] illiteracy (E4)," argues Nicolaides. The UK is the fifth most digitally advanced nation in Europe (Finland comes top) according to data from the European Union. It is already home to a large number of big tech businesses and the UK has more tech "unicorns" (start-up businesses valued at $1 billion or more) than any other European country. According to Tech Nation, a UK network focused on accelerating the growth of digital businesses across the country, in 2018 the UK continued to attract tech talent, employing 5 per cent of all high-growth tech workers globally. In Europe this places the UK behind Germany but ahead of Sweden, France, Denmark and the Netherlands. Despite (A) this encouraging news, the UK is still facing a significant digital skills shortage. A report from the Open University last year highlights the extent of the problem and its impact on UK companies, with nine in 10 organisations admitting to having a shortage of digital skills. Jules Pipe, London's deputy mayor (5) for planning, regeneration and skills, says the capital needs workers with advanced digital skills. "More than half of the capital's start-ups say a lack of highly skilled workers is their main challenge, while emerging industries -
