For those of you now eyeing your cell phones A study published in the journal suspiciously, it is worth nothing that both the Nationaoclectromagnetics reportedk no statistically Cancer Institute (sci) and the World Health Organization (WHO) say there is no evidence to support the assertion that cell phones are a public health threat. But a number of scientists are worried that there has been a dangerous rush to declared cell phones safe, using studied they feel are inadequate and too often weighted toward the wireless industry interests. An analysis published by University of Washington neurologist Henry Law determined that far more independent studied than industry-funded studics have found at least some type of biological effects from,cell-phone exposure- significant change in the incidence of brain cancer in men and women in England between 1998 and 2007, a time. when cell phone use increased dramatically But now, new work published this week in the Journal of the America Medical Association says there is an identifiable effect.of cell phone use in the brain, but it is really too early to tell what, if anything, that effect means health-wise. There has been a lot of controversy of whether cell phones could increase the temperature of the brain, which in turn could effect ebergy requirements A strong line between mobiles and cancer could have major public-health implications. As cell phones make and take calls, they exit low-level ratio- frequency (RF) radiation. Stronger than FM ratio od applications so that - our finding does signals, /these RF waves are still a billionth the intensity ofknown carcinogenic radiation like X-rays. Based on our study, we really cannot infer whether this is a bad or, could even have potentially illuminate or enlighten that very important question of whether cell phone exposure could have detrimental effects.

Kedua teks tersebut sama-sama berisi mengenai hubungan antara telepon genggam dengan kesehatan manusia yang menggunakannya, belum membahas apakah kerugian dari penggunaan telepon genggam ini sudah pada tahap terkena kanker otak. Disebutkan pada passage 4 (kalimat terakhir paragraf 1) bahwa memang telah ditemukan beberapa efek biologis dari paparan telepon genggam, tetapi belum pasti akibatnya menjadi kanker otak, lalu disebutkan juga di passage 5 (paragraf 2) bahwa ada efek yang teridentifikasi pada otak, tetapi masih belum pasti, dan yang jelas berhubungan dengan kesehatan. Dari kedua pernyataan ini, masih dibahas mengenai hubungan telepon genggam dengan kesehatan, tidak ada pernyataan efek telepon genggam memicu kanker otak, maka jawaban A yang tepat.
