With a record number of new companies starting up in Derderia and with previously established companies adding many jobs, a record number of new jobs were created last year in the Derderian economy. This year, previously established companies will not be adding as many new jobs overall as such companies added last year. Therefore, unless a record number of companies start up this year, Derderia will not break its record for new jobs created.Which of the following is an assumption on which the argument relies?

Guillemots are birds of Arctic regions. They feed on fish that gather beneath thin sheets of floating ice, and they nest on nearby land. Guillemots need 80 consecutive snow-free days in a year to raise their chicks, so until average temperatures in the Arctic began to rise recently, the guillemots' range was limited to the southernmost Arctic coast. Therefore, if the warming continues, the guillemots' range will probably be enlarged by being extended northward along the coast.Which of the following, if true, most seriously weakens the argument?

Even though vegetable meal is nutritious to fish and less costly to use than anchovy meal, most fish farmers feed their fish only anchovy meal because fish prefer its taste and consequently gain weight faster. Farmed fish would gain weight faster still on a diet consisting of a new seafood product, but this diet`s advantages did not compensate its additional cost. Nevertheless, the product`s developers predict that their product will be a commercially successful food for farmed fish.
Which of the following, if true, most helps to justify the developer`s prediction?

The price of titanium dioxide, a key ingredient in house paint, is increasing due to limited supplies because many mining companies that once produced titanium ore have shifted production to other ores. Without titanium dioxide, paint colors are less bright and more coats of paint must be applied to compensate. Companies that produce paint have concluded that they will soon need to increase the prices on the paint they produce.
Which of the following would, if true, most strongly support the companies` conclusion?
