Answer: B. True
Step-by-step explanation:
Electricity has become an integral part of education as it is needed to access various resources needed to teach. Videos, text and access to website all help one's ability to learn English and power failure can deny one the opportunity to access these resources.
Even for offline study, power is still needed because people need to be able to study outside the classroom more especially at night.
Power failure therefore inhibits the effective learning of English.
