Comparisons word choice

You re now familiar with the types of questions you will encounter. But what kinds of issues will those questions most likely deal with All of the errors that appear in Identifying Sentence Errors and Improving Sentences are fair game in Improving Paragraphs. Expect to see problems with word choice and sentence-level issues such as adjective/adverb confusion, verb tenses, faulty comparisons, and improper use of the passive voice. 

The similarity between two objects, be it persons or molecules, can be described by the degree of overlap between characteristic features of these objects. Characteristic features of human beings are, for example, the color of the hair, the weight, or the body size if the visual appearance is the focus of interest. However, if candidates applying for an open position are to be ranked, other features such as educational career or the experience in a particular profession are more important. In other words, the sensible choice of the features to be compared depends on the goal of the comparison. 

In other words, the medium-specific contribution is not easily measured or quantified for probe molecules in interaction with solid surfaces. Moreover, in the case of microporous solids, the short-distance interactions known as "confinement effects" are even more difficult to evaluate. In all comparisons of experimental data one should be aware that the reactivity of probe base molecules is largely influenced by the size of adsorbates and micropore dimensions. As a result, the acidity scales based on the free energy of proton transfer to a specific base are expected to depend on the choice of reference base. This fact has been confirmed experimentally, as calorimetric heats of adsorption of various bases on, e.g., zeolites, depend on the base chosen. For example, a ZH zeolite may be a stronger acid...
