Modern font technology provides a means to address the practical issue of needing to depict a unified Han character in terms of a collection of alternative glyph representations, in the form of Unicode variation sequences. For example, the Advanced Typographic tables of OpenType permit one of a number of alternative glyph representations to be selected when performing the character to glyph mapping process. In this case, information can be provided within plain text to designate which alternate character form to select.
What has worsened the practical aspects of unification?
A: unanswerable

In the U.S., a push for revisions of the FD&C Act emerged from Congressional hearings led by Senator Estes Kefauver of Tennessee in 1959. The hearings covered a wide range of policy issues, including advertising abuses, questionable efficacy of drugs, and the need for greater regulation of the industry. While momentum for new legislation temporarily flagged under extended debate, a new tragedy emerged that underscored the need for more comprehensive regulation and provided the driving force for the passage of new laws.
Who led the Congressional hearings in 1959?
A: Senator Estes Kefauver

Throughout the Industrial Revolution, Plymouth grew as a commercial shipping port, handling imports and passengers from the Americas, and exporting local minerals (tin, copper, lime, china clay and arsenic) while the neighbouring town of Devonport became a strategic Royal Naval shipbuilding and dockyard town. In 1914 three neighbouring independent towns, viz., the county borough of Plymouth, the county borough of Devonport, and the urban district of East Stonehouse were merged to form a single County Borough. The combined town took the name of Plymouth which, in 1928, achieved city status. The city's naval importance later led to its targeting and partial destruction during World War II, an act known as the Plymouth Blitz. After the war the city centre was completely rebuilt and subsequent expansion led to the incorporation of Plympton and Plymstock along with other outlying suburbs in 1967.
What nearby settlement built ships for the Royal Navy?
A: Devonport

The lowest pressure that can be attained in a system is also dependent on many things other than the nature of the pumps. Multiple pumps may be connected in series, called stages, to achieve higher vacuums. The choice of seals, chamber geometry, materials, and pump-down procedures will all have an impact. Collectively, these are called vacuum technique. And sometimes, the final pressure is not the only relevant characteristic. Pumping systems differ in oil contamination, vibration, preferential pumping of certain gases, pump-down speeds, intermittent duty cycle, reliability, or tolerance to high leakage rates.
How can chamber geometry be connected?
A:
unanswerable
