text_A: When Hurricane Sandy made landfall in New Jersey on October 29, 2012, the effects were severe, and Mantoloking was especially hard hit, with more than 50 homes requiring demolition, accounting for almost 10% of the housing units in the borough as of the 2010 Census. Verizon Communications announced in July 2013 that it had decided against providing Mantoloking residents with "plain old telephone service" from replacement copper-wire lines, and had decided instead to provide them with its Voice Link wireless service, an effort that brought protests from the AARP. Residents have complained that many calls don't go through when dialed, that fax transmissions cannot be made, that 911 calls may be affected by network bottlenecks and that power outages would result in the loss of service.
text_B: If Hurricane Sandy had never occurred, Mantoloking had kept its original infrastructure, and Verizon had made this decision simply as an ongoing business matter, would the decision have left local residents less vulnerable to floods or even freak earthquakes that could affect underground telephone lines?
YES.
