The legal administration of the death penalty in the United States is complex. Typically, it involves four critical steps: (1) sentencing, (2) direct review, (3) state collateral review, and (4) federal habeas corpus. Recently, a narrow and final fifth level of process – (5) the Section 1983 challenge – has become increasingly important. (Clemency or pardon, through which the Governor or President of the jurisdiction can unilaterally reduce or abrogate a death sentence, is an executive rather than judicial process.) The number of new death sentences handed down peaked in 1995–1996 (309). There were 73 new death sentences handed down in 2014, the lowest number since 1973 (44).
If it is possible to answer this question, answer it for me (else, reply "unanswerable"):  In what year were there 73 death penalty convictions overturned?
Ah, so.. unanswerable

LEDs have also been used as a medium-quality voltage reference in electronic circuits. The forward voltage drop (e.g. about 1.7 V for a normal red LED) can be used instead of a Zener diode in low-voltage regulators. Red LEDs have the flattest I/V curve above the knee. Nitride-based LEDs have a fairly steep I/V curve and are useless for this purpose. Although LED forward voltage is far more current-dependent than a Zener diode, Zener diodes with breakdown voltages below 3 V are not widely available.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What LEDs have a very steep I/V curve?
Ah, so.. Nitride-based LEDs

One adaptation helping both predators and prey avoid detection is camouflage, a form of crypsis where species have an appearance that helps them blend into the background. Camouflage consists of not only color but also shape and pattern. The background upon which the organism is seen can be both its environment (e.g., the praying mantis to the right resembling dead leaves) or other organisms (e.g., zebras' stripes blend in with each other in a herd, making it difficult for lions to focus on a single target). The more convincing camouflage is, the more likely it is that the organism will go unseen.

Ah, so..
