26	Educational policy analyst: To improve the long-term economic benefits that our country’s universities provide to their students, the government should provide subsidies enabling the universities to hire more academic staff. Hiring more academic staff would allow smaller class sizes. Statistically, university students in smaller classes tend to receive higher grades than those in larger classes. And on average, a student who earns higher grades in university classes tends to have a higher salary after graduation than a student who earns lower grades. Thus, hiring more academic staff nationwide should improve the economic wellbeing of graduates nationwide.Consider the incomplete statement:According to the analyst's argument, students’ 1 is bolstered by their 2.Select for 1 and 2 the options that complete the statement in the manner that most accurately reflects the given information. Make only two selections, one in each column.
27	The diagram shows a project team consisting of exactly 8 workers. Each worker is represented by a circle labeled with a capital letter. An arrow directed from one worker’s circle to a second worker’s circle indicates that the first worker directs project-related questions to the second worker. Each of the workers to whom no other worker directs project-related questions is an individual contributor, and each worker to whom one or more of the other workers directs project-related questions is a coordinator. For example, G (an individual contributor) directs project-related questions to E (a coordinator), but E does not direct project-related questions to G; whereas C and D (both coordinators) direct project-related questions to one another. Use each drop-down menu to create the most accurate statement about this project team based on the information provided.10A. There are exactly individual contributors on the project team.10B. and the individual contributor who directs project-related questions to the greatest number of other workers is .
28	Each of the species of a certain type of insect has at least one of five significant traits: A, B, C, D, and E. Furthermore, one study has determined that any species with Trait A has at least one of the Traits B and C. Another study has determined that any species with Trait C has at least one of the Traits D and E. And a third study has determined that any of the species with Trait B has Trait C. The results of each study are correct.Select different options for X and for Y such that the following statement most accurately describes the passage. Make only two selections, one in each column.In addition to the relationship between Traits B and C that is stated explicitly with respect to the third study, the passage implies that any of the insects that has Trait ____ X ____ also has Trait ____ Y ____.
