question:
Context: When you take a walk along a beach, what do you find there? Sand, the ocean, lots of sunlight. You may also find shells. The shells you find are most likely left by organisms in the phylum Mollusca. On the beach, you can find the shells of many different mollusks ( Figure 1.1), including clams, mussels, scallops, oysters, and snails. Mollusks are invertebrates that usually have a hard shell, a mantle, and a radula. Their glossy pearls, mother of pearl, and abalone shells are like pieces of jewelry. Some mollusks, such as squid and octopus, do not have shells. The Mollusks body is often divided into different parts ( Figure 1.2): On the beach, you can find a wide variety of mollusk shells. 1. A head with eyes or tentacles. 2. In most species, a muscular foot, which helps the mollusk move. Some mollusks use the foot for burrowing into the sand, and others use it for jet-propulsion. 3. A mantle, or fold of the outer skin lining the shell. The mantle often releases calcium carbonate, which creates an external shell, just like the ones you find on the beach. The shell is made of chitin, a tough, semitransparent substance. 4. A mass housing the organs. 5. A complete digestive tract that begins at the mouth and runs to the anus. 6. Most ocean mollusks have a gill or gills to absorb oxygen from the water. 7. Many species have a feeding structure, the radula, found only in mollusks. The radula can be thought of as a "tongue-like" structure. The radula is made mostly of chitin. Types of radulae range from structures used to scrape algae off of rocks to the beaks of squid and octopuses. This is the basic body plan of a mollusk. Note the mantle, gills, and radula. Keep in mind the basic body plan can differ slightly among the mollusks. Mollusks are probably most closely related to organisms in the phylum Annelida, also known as segmented worms. This phylum includes the earthworm and leech. Scientists believe these two groups are related because, when they are in the early stage of development, they look very similar. Mollusks also share features of their organ systems with segmented worms. Unlike segmented worms, however, mollusks do not have body segmentation. The basic mollusk body shape is usually quite different as well. 
 Question: the foot of a squid is probably used for
answer:
jet-propulsion.


question:
Context: The Rams started their season on the road against the Lions. The Rams drew first blood in the first quarter with a 48-yard field goal from Greg Zuerlein to take a 3-0 lead for the only score of that quarter. The Lions then took a 7-3 lead with Joique Bell's 1-yard run for a touchdown in the 2nd quarter. The Rams responded with a 29-yard field goal from Zuerlein as they came up within a point 7-6 before on the Lions' next possession, Matthew Stafford was picked off by Cortland Finnegan and it was returned 31 yards for a touchdown as the Rams retook the lead 13-7. The Lions then responded with Jason Hanson kicking a 41-yard field goal to shorten the Rams' lead to 13-10 at halftime. After the break, the Lions scored first with Jason Hanson kicking a 45-yard field goal to tie the game 13-13 for the only score of the 3rd quarter. However, the Rams moved back into the lead in the 4th quarter with Brandon Gibson's 23-yard catch from Sam Bradford to make it 20-13. The Lions tied the game back up with Kevin Smith running for a touchdown from 5 yards out to tie the game 20-20. The Rams then retook the lead with Greg Zuerlein kicking a 46-yard field goal to make the score 23-20. On their last possession, the Lions moved down the field and Matthew Stafford found Kevin Smith on a 5-yard touchdown pass to make the final score 27-23 as the Rams began their season 0-1. 
 Question: Who kicked the longest field goal in the last quarter?
answer:
greg zuerlein


question:
Context: Opioid overdose is rarely the primary cause of altered mental status in cancer patients receiving opioid therapy. The inappropriate administration of naloxone to reverse an abnormal mental status can cause severe withdrawal symptoms and pain. To illustrate this problem, we report the case of a patient inappropriately treated with naloxone and the results of a retrospective review of the medical records of 15 consecutive patients with cancer treated with naloxone in the emergency department over a 5-month period. We offer guidelines for a more thoughtful approach to the management of patients with cancer who present with encephalopathy. 
 Question: Which medication should be administered when managing patients with suspected acute opioid overdose?
answer:

naloxone
