A new device uses the global positioning system to determine a cow's location and, when a cow strays outside of its pasture, makes noises in the cow's ears to steer it back to its home range. Outfitting all of the cattle in a herd with this device is far more expensive than other means of keeping cattle in their pastures, such as fences. The device's make nevertheless predicts that ranchers will purchase the
device at its current price.
Which one of the following, if true, does the most to support the prediction made by the device's maker?
Pre-Thinking : GPS system might have more advantage than other means, Maybe reusability due to which the actual costs are less. So we should focus on this point. A)The price will come down appreciably if the device's maker is able to produce it in large quantities.
Irrelavent, Conclusion talks about purchasing it at the current price. So this option is irrelaventB)As they graze, cattle in a herd follow the lead of the same few members of the herd.
Yeah, If this is true then we won't need GPS devices for all the cattle. Hence it can bring down the total cost and may be favorable than existing methods C)The device has been shown not to cause significant stress to cattle.
OFS, Not bothered about thatD)The device has been shown to be as effective as fences at keeping cattle in their pastures.
Yeah, But why to pay more money if it is equally effectiveE)The device's maker offers significant discounts to purchasers who buy in bulk.
Irrelavent, Same reason as Option A
