King recognizes the need for qualifications: verbs in the problematic class can have the content reading with certain special NPs, e.g., quantifiers ('everything Bill holds, Bob holds'), and anaphoric pronouns ('I hold that, too'.).
One on-going approach to resolve the overall metazoan phylogeny, as well as the problematic class-level relationships among the sponges, has been comparative analysis of mitochondrial genomes (mtDNA).
Or if that's impossible, consider dropping another class or extracurricular activity so you'll have more time and energy to devote to the problematic class.
You might consider dropping the most problematic classes and take a lighter load of classes.
The most problematic class was the chemical class multiple.
With the suggested extension, formerly problematic classes such as 'synapse' can be subsumed unambiguously under one of the additional categories ('fiat cell part aggregate' in case of 'synapse'synapse
To reduce medication effects, we recruited euthymic patients that were not receiving antipsychotics, which are likely to be the most problematic class for studying reward processing (Pessiglione et al., 2006; Abler et al., 2007 b ).
The belief that the bad smells are linked with problematic classes is largely based on previous metric research results.
However, their high chemical stability, persistence, pronounced lipophilicity, and tendency to bioaccumulate, as well as their extensive technical production and use from 1929 to the 1970s, still make PCBs one of the world's most widespread and problematic classes of environmental contaminants (Erickson 2001; Safe 1993).
Some particularly problematic classes refer to the relative arrangement of parts or attachments within the whole molecule.
