PROBLEM: What is the sentiment of the following document towards the entity Aranibar ? Bitter potato varieties are still harvested in the Andean highlands  says Marcelino Aranibar  an animal nutritionist and vice president of research at the National University of Juliaca. Especially at higher altitudes  these hardy and frost-resistant varieties are a valuable food source.
Instead of detoxifying them with clay alone  Aranibar says these bitter potatoes are often made into chuño  a form of naturally dehydrated potato that also removes some of the toxins. Making chuño is considered an ancient Andean practice and allows for year-round potato storage.
 Aranibar  has researched how rats with gastritis recuperate after being fed chaco  though  he  has not researched this in humans.  Aranibar himself  eats the pale tan or grey clay mixed with water once every day or two.  He  claims it has helped manage  his  own gastritis.
The practice of clay eating is now a part of the region's tradition  says  Aranibar .
"There are many people in the Peruvian-Bolivian high plateau that still consume clay  but it's not because the potatoes are bitter "  he  says. "It is more of a custom than a necessity."

PROBLEM: What is the sentiment of the following document towards the entity Kelly Gallivan ? It was October.  Kelly Gallivan   68  remembers seeing the Amazon box addressed to  her  husband sitting outside their Acton  Massachusetts  house.  She  brought it inside  opened it and unwrapped the "techy gizmo stuff."
"What did you order this for?"  she  remembers asking  her  70-year-old husband.
But  Mike Gallivan  hadn't ordered them. It was easy for the couple to forget about the puzzling package - until many others started arriving.
More than 20 boxes have been sent to the house  all addressed to  Mike Gallivan   none containing the sender's name or invoices or receipts. The gadgets have started piling in a corner of their house: Phone chargers  USB cords  an outdoor TV plastic cover  a computer vacuum cleaner  a humidifier powered by a USB  a Bluetooth speaker  tent lamps  high-intensity flashlights  a rechargeable dog collar. The most recent one came last Thursday   Kelly Gallivan  said.
"At first it was kind of weird. Then kind of funny. Then kind of creepy  " Kelly Gallivan  said. "We don't want this stuff. Some of it's trash  some it's pretty good stuff. But we just don't want this stuff and its just an uncomfortable feeling that we keep getting these things."
The Gallivans aren't sure how much longer they'll keep receiving the packages. Some items have been well-received - Mike Gallivan said he plans to use the high-intensity flashlight and a pair of Bluetooth headphones. Other gadgets  like a "little gizmo you put around your cellphone that lights up the area when you want to take your selfie " Kelly Gallivan said  will likely be donated.
