4. No.3  (Original) Economics (plays, play) a major role in many business decisions.  (Revised) Economics plays a major role in many business decisions.

5. No.4  (Original) Everybody (try, tries) to create and market a product during the course.  (Revised) Everybody tries to create and market a product during the course.

6. No.5  (Original) One of the hidden nodes that (was, were) implemented in the neural network learning algorithms (was, were) extensively studied.  (Revised) One of the hidden nodes that were implemented in the neural network learning algorithms was extensively studied.

7. No.6  (Original) There (is, are) many topic to be covered during the seminar.  (Revised) There are many topic to be covered during the seminar.

8. [Note 2.7]  The noun following the verb determines whether the verb is singular or plural since there is or there are is not the subject.  If you are still confused as to whether a sentence beginning with There takes a singular or plural form, place the subject in front of the sentence. Consider the following example:

9. [Note 2.7] (cont.)  (Original) There (is, are) many computer courses available at the university.  (Revised) Many computer courses available at the university.  Placing the subject in front of the sentence makes it clear as to whether the verb should take a singular or plural from.

10. No.7  (Original) Verification of the generalization capability of the neural model, along with identification of the best forecast of the performance measure, (demonstrates, demonstrate) the efficiency of the network in establishing the optimal parameter society.

11. No.7 (cont.)  (Revised) Verification of the generalization capability of the neural model, along with identification of the best forecast of the performance measure, demonstrates the efficiency of the network in establishing the optimal parameter society.

12. No.8  (Original) A number of parameter setup values in a gas-assisted injection molding process (are, is) identified.  (Revised) A number of parameter setup values in a gas-assisted injection molding process are identified.

13. No.9  (Original) Evaluation of the effect of various parameters and identification of the optimal parameter setup values in a gas-assisted injection molding process (is,are) performed in this study.  (Revised) Evaluation of the effect of various parameters and identification of the optimal parameter setup values in a gas-assisted injection molding process are performed in this study.

14. No.10  (Original) The majority of the group (confers, confer) with the school’s decision.  (Revised) The majority of the group confers with the school’s decision.

15. [Note 2.8]  Avoid wordiness by saying Most instead of The majority of.
