Problem: Text: An acoustic-electric guitar (also called an electro-acoustic guitar) is an acoustic guitar fitted with a magnetic pickup, a piezoelectric pickup or a microphone. In electric-acoustic nylon string guitars, piezoelectric pickups and microphones are always used because magnetic pickups are not capable of picking up vibrations of non-magnetic materials. The design is distinct from a semi-acoustic guitar, which is an electric guitar but with the addition of sound chambers within the guitar body. Usually, acoustic-electric guitars are fitted with piezoelectric pickups, and hence require a preamplifier incorporated into the guitar body to amplify the signal before it travels to the main guitar amplifier. These preamps may also come with tone controls of varying types, but usually equalizers with up to six frequency bands are used. They are also referred to as a ''plug-in acoustic guitar'', due to their ability to simply ''plug in'' to a speaker system without the need for microphones.

Question: can a guitar be both acoustic and electric?

OPTIONS:
- no
- yes
A: yes

Problem: Text: In golf, a hole in one or hole-in-one (also known as an ace, mostly in American English) is when a ball hit from a tee shot finishes in the cup. This awards the player a score of one for the hole. Holes in one most commonly occur on par 3 holes, the shortest distance holes on a standard size golf course. Longer hitters have also accomplished this feat on longer holes, though nearly all par 4 and par 5 holes are too long for golfers to reach in a single shot. While well known outside of golf and often requiring a well hit shot and significant power, holes in one are considered to also contain an element of luck. As such, they are more common and considered less impressive than other hole accomplishments such as completing a par 5 in two shots (an albatross). As of October 2008, a condor (four under par) hole-in-one on a par 5 hole had been recorded on four occasions, aided by thin air at high altitude, or by cutting the corner on a doglegged or horseshoe-shaped hole.

Question: has anyone ever made a hole in one on a par 5?

OPTIONS:
- no
- yes
A:
yes
