Final answer:
The author's reasons for avoiding British schools include safety concerns, systemic barriers to education, the high expense of schooling, and cultural and health implications.
Step-by-step explanation:
The author has several reasons for avoiding British schools which can be inferred from the context provided. Issues such as safety concerns due to kidnappings, difficulty in obtaining a thorough education because of exclusion from certain institutions, economic challenges due to the expense of schooling, alongside issues of cultural imperialism and inadequate healthcare at some schools, come forth in the excerpts.
For instance, the mention of boarding schools becoming dangerous due to kidnappings or other troubles is a significant deterrent. Similarly, the statement "He has denied her the facilities for obtaining a thorough education-all colleges being closed against her" suggests systemic barriers to education.
Moreover, the financial burden is evidenced by the concerns raised about campaign expenditures and the inaccessibility of college due to the high cost for many families in Pakistan. In addition, an important concern is the cultural and health implications of attending certain schools, as described in the excerpt discussing children's exposure to diseases and cultural imperialism.
