Task: Table-QA (source dataset: FinQA)

Task: 
You are given a table containing structured data and a natural language question referring to the table. Your goal is to analyze the table and provide an accurate and concise answer based on the given data.

Instructions:
1. Understand the Table: Examine the structure, headers, and data in the table. Identify relevant columns and rows related to the question.
2. Interpret the Question: Determine whether the question requires direct retrieval, aggregation, comparison, sorting, filtering, or inference.
3. Extract the Answer: Use logical reasoning and numerical operations (if necessary) to derive the correct response from the table.
4. Format the Answer: No explanation, return the answer in a structured JSON format: {"answer": <answer>}. If the question cannot be answered due to missing or ambiguous data, return a JSON response with {"answer": null}.

Question:
what was the ratio of the tons hedged in 2017 to 2018


pre_text: republic services , inc .
notes to consolidated financial statements 2014 ( continued ) the following table summarizes our outstanding costless collar hedges for occ as of december 31 , 2016 : year tons hedged weighted average floor strike price per ton weighted average cap strike price per ton .
post_text: costless collar hedges are recorded in our consolidated balance sheets at fair value .
fair values of costless collars are determined using standard option valuation models with assumptions about commodity prices based upon forward commodity price curves in underlying markets ( level 2 in the fair value hierarchy ) .
we had no outstanding recycling commodity hedges as of december 31 , 2015 .
the aggregated fair values of the outstanding recycling commodity hedges as of december 31 , 2016 were current liabilities of $ 0.8 million , and have been recorded in other accrued liabilities in our consolidated balance sheets .
no amounts were recognized in other income , net in our consolidated statements of income for the ineffective portion of the changes in fair values during the years ended december 31 , 2016 , 2015 and 2014 .
total loss recognized in other comprehensive income for recycling commodity hedges ( the effective portion ) was $ ( 0.5 ) million for the year ended december 31 , 2016 .
no amount was recognized in other comprehensive income for 2015 .
total gain recognized in other comprehensive income for recycling commodity hedges ( the effective portion ) was $ 0.1 million for the year ended december 31 , 2014 .
fair value measurements in measuring fair values of assets and liabilities , we use valuation techniques that maximize the use of observable inputs ( level 1 ) and minimize the use of unobservable inputs ( level 3 ) .
we also use market data or assumptions that we believe market participants would use in pricing an asset or liability , including assumptions about risk when appropriate .
the carrying value for certain of our financial instruments , including cash , accounts receivable , accounts payable and certain other accrued liabilities , approximates fair value because of their short-term nature. .
