Sense for a switch closure and then go for a delay and then come back and see if the switch is still pushed

Sense for a switch closure and then read the switch instantly

Can't be solved

To compare 2 voltage and report which is larger.

To filter out the analogue signal.

To filter out the digital signal. 

To sum up the voltage.

the wire should be aluminium

the wire should be tinned copper wire

the wire should be gold coated

tiny "U" shaped springs that clamp on the leads of the components

copper tracks

liquid metal such as mercury that makes a frictionless contact

are electrically connected to each other

are not electrically connected to each other. They are conventionally used as supply and ground rails.

will make a good contact

will have no affect on the circuit

may make a contact but it will be unreliable

you can insert them straight into the board with no effect

none of the above

you should cut the part of the lead off that has been in the tape as it has probably been contaminated with glue. This will de-rate the quality of your bread board.

can plug straight into the bread board

must first be soldered to a carrier board and then plugged into the bread board

cannot be used on a bread board circuit

bend the leads of the component in two to double the thickness

solder leads on the component that are within specification
