NL: Inherit attributes from context

[pradh]

[countries in the world with the highest mortality rates] -> [show me the lowest]

But [show me the lowest among the countries] works.

Another case:

Query sequence used: https://autopush.datacommons.org/nl#q=are%20there%20any%20cyclones%20in%20asia;i%20want%20to%20know%20about%20the%20education%20rate%20in%20america;how%20about%20these%20rates%20in%20europe(https://autopush.datacommons.org/nl/#q=are%20there%20any%20cyclones%20in%20asia;i%20want%20to%20know%20about%20the%20education%20rate%20in%20america;how%20about%20these%20rates%20in%20europe&a=true)&a=true

Note that the third query says: "how about these rates in europe". The user is referring to their previous query (context) but the current query does not use the past context.

This is a difficult case because there are many ways to refer to the previous context.
