[quote="VeritasPrepBrian"]The countable / uncountable "can you count it?" thing is a helpful tool, but it's not as hard-and-fast a rule. What countable/uncountable really does is tell the reader how to treat the quantity/amount.

Here is my take at it.
sources of alternate income ==can you count it(just learned from Brian) ..yes ..so fewer will come here .
This quickly eliminates B and D.Now we need to select between choice between lesser than and less than.
Note :Option C is tricky..lesser than ...vs fewer (its temping to make it parallel..adjective..adjective)
but its of course fatal
"LESS vs Lesser than usage"Less is the comparative form of little and is normally used only with uncountable nouns*:
I have $20.00. Jack has $30.00. I have less money than Jack.
Lesser is an comparative adjective used only before a noun.
It means ""not as large,"" ""not as important,"" or ""not as much"" as something else:
The current global food crisis is creating hardships for people everywhere, but people
in developed countries are
suffering to a lesser degree than people in the underdeveloped parts of the world
""Lesser"" refers to the diminished importance of something, NOT to the amount of something.(genneraly before noun)...They originally asked for $5 million, but finally settled for a lesser sum
"
So this means we cannot use lesser than for the amount of something .This means E is out.
Now we are left with option A and E.
Amount fewer than 15000 means ur counting the units of dollar..But it actually can be in decimal or cents ..
Finally we are left with only option A.
Press Kudos if it helps !!
