The second point in the paragraph about children provides more support for the overall topic: noise pollution. because it's offering more evidence that noise pollution is an issue, "furthermore" is your best choice as a transition. "for instance" would suggest that you're giving an example of something, as in a specific case in which a child's education suffered. "however" suggests a shift, usually describing an exception, and the point of the children's education is not an exception--it's further evidence. "consequently" suggests that you'd carry on to tell the reader about an effect of a circumstance.
Answer: Standard time is the synchronization of clocks within a geographical region to a single time standard, rather than a local mean time standard. Generally, standard time agrees with the local mean time at some meridian that passes through the region, often near the center of the region. Historically, standard time was established during the 19th century to aid weather forecasting and train travel. Applied globally in the 20th century, the geographical regions became time zones. The standard time in each time zone has come to be defined as an offset from Universal Time. A further offset is applied for part of the year in regions with daylight saving time.
The adoption of standard time, because of the inseparable correspondence between time and longitude, solidified the concept of halving the globe into an eastern and western hemisphere, with one prime meridian replacing the various prime meridians that had previously been used.
