Given the Question and Answer pair, detect whether the answer is acceptable or not. Denote acceptable answer as "yes", otherwise denote as "no". An acceptable answer is consistent with the context in question, detailed, long, and uses general knowledge of English. Answers that are not definite and suggest a variety of options are not acceptable answers.

Ex Input:
Question: Suppose I tell something to my companion and I want to make sure he understands me. I thought I may simply ask "Do you understand me?". But recently I heard that in such cases I should ask "Does that make sense?" instead. Is this true? Which option is appropriate to use in business communication? 
Answer: "Do you understand me?" slightly carries the implication that it is your fault if you do not understand. "Does it make sense?" carries the implication that it is my fault if you do not understand. So politeness suggests that the latter is better.

Ex Output:
yes

But recently I heard that in such cases I should ask "Does that make sense?" instead. Is this true? Which option is appropriate to use in business communication? 
Answer: I generally go with a simple: Is this explanation okay..? As it sounds neutral and encourages the receiver to provide feedback. If I used pronouns while asking for feedback, like "Did you understand..", "Did I explain this..", .. it generally makes the receiver feel like you might take their feedback negatively or take offense if they were not able to understand.

Ex Output:
no


Ex Input:
Question: I need a single-word to describe something good that (unexpectedly) resulted from something bad. This good thing could not have occurred without the bad event happening first, as a precursor. Example sentence: "I got in a horrible car accident and broke my leg, but falling in love with my nurse at the hospital was the ____," (something like that). 
Answer: silver lining "I got in a horrible car accident and broke my leg, but falling in love with my nurse at the hospital was the silver lining" From Wikipedia A silver lining is a metaphor for optimism in the common English-language which means a negative occurrence may have a positive aspect to it. Etymonline says: a "bright side" which proverbially accompanies even the darkest trouble; by 1843, apparently from oft-quoted lines from Milton's "Comus," where the silver lining is the light of the moon shining from behind the cloud. Was I deceived? or did a sable cloud Turn forth her silver lining on the night? I did not err, there does a sable cloud, Turn out her silver lining on the night And casts a gleam over this tufted grove. To which Thomas Warton added the commentary: "When all succour eems to be lost, Heaven unexpectedly presents the ilver lining o a able cloud to the virtuous.".

Ex Output:

yes
