Earthworms make a significant contribution to soil fertility. The rear end of the Palolo worm, a marine polychaete that tunnels through coral, detaches in order to spawn at the surface, and the people of Samoa regard these spawning modules as a delicacy. Anglers sometimes find that worms are more effective bait than artificial flies, and worms can be kept for several days in a tin lined with damp moss. Ragworms are commercially important as bait and as food sources for aquaculture, and there have been proposals to farm them in order to reduce over-fishing of their natural populations. Some marine polychaetes' predation on molluscs causes serious losses to fishery and aquaculture operations.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What do some polychaetes eat that is harmless?
Ah, so.. unanswerable

The GameCube and Wii versions feature several minor differences in their controls. The Wii version of the game makes use of the motion sensors and built-in speaker of the Wii Remote. The speaker emits the sounds of a bowstring when shooting an arrow, Midna's laugh when she gives advice to Link, and the series' trademark "chime" when discovering secrets. The player controls Link's sword by swinging the Wii Remote. Other attacks are triggered using similar gestures with the Nunchuk. Unique to the GameCube version is the ability for the player to control the camera freely, without entering a special "lookaround" mode required by the Wii; however, in the GameCube version, only two of Link's secondary weapons can be equipped at a time, as opposed to four in the Wii version.[g]
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Aside from the sword, what is another weapon that Link can use?
Ah, so.. Nunchuk

Foot resigned and was replaced as leader by Neil Kinnock, with Roy Hattersley as his deputy. The new leadership progressively dropped unpopular policies. The miners strike of 198485 over coal mine closures, for which miners' leader Arthur Scargill was blamed, and the Wapping dispute led to clashes with the left of the party, and negative coverage in most of the press. Tabloid vilification of the so-called loony left continued to taint the parliamentary party by association from the activities of 'extra-parliamentary' militants in local government.

Ah, so..
Arthur Scargill
