Answer:
First, let's add the missing piece- the article
"Well, we haven’t read the articles yet, but I have their titles here. You can read them,” Alana said as she handed a paper to her mother with the following list:
1. Long-Term Cell Phone Use Spurs Tumor Growth
2. Mobile Phone Use and Acoustic Neuroma
3. Study Links Mobile Phones, Benign Tumors
4. Cell Phone-Tumor Link Found?
5.Study Indicates Mobile Phones Increase Tumor Risk
“Now I’m even more confused. Do cell phones cause cancer or not? Can I use mine or not?” asked Alisa impatiently.
“In my next class we’re going to read the articles, so I will tell you everything then,” concluded her sister.
Then the Answer to our question:
Both headlines 4 and 5 outline the exact same way, with little or no difference in the headline structure. On a closer look, we can infer that scientific research 4 looks less definite in a risk being found research. Unlike 5 which looks more definite in combining mobile phones with acoustic neuroma.
