この英文から、なぜ筆者のプランは毎月100ドル以上かかったと言えないのか教えてほしいです

B You are a college student going to study in the US and need travel insurance. You find this review of an insurance plan written by a female international student who studied in the US for six months. 0 There are many things to consider before traveling abroad: pack appropriate clothes, prepare your travel expenses, and don't forget medication (if necessary). Also, you should purchase travel insurance. Imam gavo 0012 1ovo od 1200 sla When I studied at Fairville University in California, I bought travel insurance from TravSafer International. I signed up online in less than 15 minutes and was immediately covered. They accept any form of payment, usually on a monthly basis. There were three plans. All plans include a one-time health check-up. gisinal The Premium Plan is $100/month. The plan provides 24-hour medical support through a smartphone app and telephone service. Immediate financial support will be authorized if you need to stay in a hospital. It had the 24-hour telephone The Standard Plan worked best for me. assistance and included a weekly email with tips for staying healthy in a foreign country. It wasn't cheap: $75/month. However, it was nice to get the optional 15% discount because I paid for six months of coverage in advance. If your budget is limited, you can choose the Economy Plan, which is $25/month. It has the 24-hour telephone support like the other plans but only covers emergency care. Also, they can arrange a taxi to a hospital at a reduced cost if considered necessary by the support center. I never got sick or hurt, so I thought it was a waste of money to get insurance. Then my friend from Brazil broke his leg while playing soccer and had to spend a few days in a hospital. He had chosen the Premium Plan and it covered everything! I realized how important insurance is-you know that you will be supported when you are in trouble.
