>>Hi everybody,

>>I am trying to help my son in 5th grade and can not figure this out.

>>He has the following words:
>>
>>accomplice, exultant, remorseless, sedate, apprehension, ponderous, revulsion.
>>
>>And we need to figure out this sentence:
>>
>>Sweet is to sour as ... is to light.
>>
>>We figured out all other examples, but this one I can not understand using the words I listed. I've checked each word in the dictionary as they are not easy to me as well.
>>
>>Thanks in advance.

>Try ponderous.
