Structure of sentences IV: Restrictive vs. nonrestrictive modification
Modified Exercise
14-1. Restrictive and nonrestrictive modifiers.
Here are ten examples of misused or
ambiguous restrictive or nonrestrictive modifiers taken from GSO student
abstracts and the literature. Explain what is wrong with each sentence and
rewrite it to convey the meaning intended (if you can determine it).
1. [Scyliorhinus retifer’s] small size and ability to thrive in captivity make it an excellent subject for laboratory studies which can not be done with most other shark species.
2. This model is composed of a stack of constant density layers, making it well suited to considering the motion of isopycnal, Lagrangian particles.
3. For both solids, Sh’ first increased or stayed the same and then decreased with increasing θn while Shapt generally decreased with decreasing θn.
4. United States Federal Regulations, required for compliance with the Hazardous and Solid Waste Act, direct the permittee to propose Media Protection Standards for hazardous chemicals that may have been released from their facility.
5. The Mid-Atlantic Ridge in the North Atlantic between 28 N and 70 N overlies two geochemically distinct mantle domains dominated by the Iceland and Azores mantle plumes.
6. Massachusetts Bay had the highest human population density of 8.1 persons ha-1.
7. The fastest growing unstable modes are always the lowest modes having an amplitude maximum near 50 m depth.
8. Constraints on physical conditions within the 1883 magma chamber have been determined from volatile concentrations within melt inclusions and plagioclase-liquid equilibria indicating a minimum total pressure of 1.0–1.5 kbar.
9. However, DOC concentrations varied by as much as a factor of three over spatial and temporal scales suggesting a relatively dynamic DOC pool.
10. It is also possible that these shifts reflect an increase in the relative contribution of petrol lead emitted in East and Central European countries where local emissions are much higher and the isotopic composition of lead is consistent with the observed changes in Paris and Oslo.
