Lions and great white sharks may boast the most famous jaws in the animal kingdom—but theirs are nowhere near the fastest. That honor belongs to Odontomachus bauri, a tiny ant whose jaws can snap shut at a remarkable 145 miles per hour. The ant’s quick bite also does double-duty as an escape mechanism. When faced with a larger nest intruder, an ant may use its jaws to strike the invader, simultaneously flinging itself 8 or 9 inches away (a maneuver known as the “bouncer defense”). Therefore, it may snap its jaws against the ground, propelling itself into the air and out of the way of such dangers as an anteater’s tongue (a move known as an “escape jump”).

 

A. NO CHANGE
B. For example,
C. Alternatively,

Life as we know it requires liquid water, which can exist on planets with a surface temperature and a mass similar to the Earth’s.

In 1850, Joel Houghton registered a patent for the first mechanical dishwasher in the United States. The device was made of wood and was cranked by hand while water sprayed onto the dishes, and they were both slow and unreliable. Fifteen years later, another patent was granted to L.A. Alexander. It was similar to the first but featured a hand-cranked rack system. Like Houghton’s, this contraption was neither practical nor widely accepted.

In recent years, scientists have become increasingly aware that plants thrive through cooperation rather than competition. For example, oaks that are subjected to drought conditions have been shown to provide nutrition to their beneficial partners by transferring water from their tap roots up through their root systems to associated fungal networks, nourishing these beneficial partners. In fact, some researchers believe that such networks are the principal way that plants extract nutrients from the soil.

 

 

A. NO CHANGE
B. providing nourishment for these beneficial partners.
C. sustaining these beneficial partners.
D. DELETE the underlined portion (replacing the comma after networks with a period).

When I was a child growing up on the Eastern Shore of Maryland, crossing a big bridge meant facing unexpected challenges. The majestic Chesapeake Bay Bridge was my family’s main route off of the rural shore and towards “real cities,” where we could walk among crowds and shop in stores unlike anything we had at home. But these trips were also journeys in themselves— a chance to spot bottlenose dolphins and peregrine falcons and to see both our home and our destination from a new perspective.

B. environments that make it unnecessary for search teams to use metal detectors like the Arizona desert.
C. environments like the Arizona desert, making it unnecessary for search teams to use metal detectors.

In the past few years, governments have begun to see automation as the key to better urban futures. Many cities are becoming test-beds for experiments with robots in social spaces, where robots have both a practical purpose (for which they are programmed) and a symbolic role (to demonstrate good city governance). Whether through autonomous cars, automated pharmacists, service robots in local stores, or autonomous drones delivering parcels, cities are being automated at a steady pace.
