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:
scalable infrastructure represents what percent of capital expenditures incurred the cable segment during 2007?


pre_text: facility due 2013 relates to leverage ( ratio of debt to operating income before depreciation and amortization ) .
as of december 31 , 2008 , we met this financial covenant by a significant margin .
our ability to comply with this financial covenant in the future does not depend on further debt reduction or on improved operating results .
share repurchase and dividends as of december 31 , 2008 , we had approximately $ 4.1 billion of availability remaining under our share repurchase authorization .
we have previously indicated our plan to fully use our remaining share repurchase authorization by the end of 2009 , subject to market conditions .
however , as previously disclosed , due to difficult economic conditions and instability in the capital markets , it is unlikely that we will complete our share repurchase authorization by the end of 2009 as previously planned .
share repurchases ( in billions ) 20072006 our board of directors declared a dividend of $ 0.0625 per share for each quarter in 2008 totaling approximately $ 727 million .
we paid approximately $ 547 million of dividends in 2008 .
we expect to continue to pay quarterly dividends , though each subsequent dividend is subject to approval by our board of directors .
we did not declare or pay any cash dividends in 2007 or 2006 .
investing activities net cash used in investing activities consists primarily of cash paid for capital expenditures , acquisitions and investments , partially offset by proceeds from sales of investments .
capital expenditures our most significant recurring investing activity has been capital expenditures in our cable segment and we expect that this will con- tinue in the future .
a significant portion of our capital expenditures is based on the level of customer growth and the technology being deployed .
the table below summarizes the capital expenditures we incurred in our cable segment from 2006 through 2008. .
post_text: ( a ) customer premises equipment ( 201ccpe 201d ) includes costs incurred to connect our services at the customer 2019s home .
the equipment deployed typically includes stan- dard digital set-top boxes , hd set-top boxes , digital video recorders , remote controls and modems .
cpe also includes the cost of installing this equipment for new customers as well as the material and labor cost incurred to install the cable that connects a customer 2019s dwelling to the network .
( b ) scalable infrastructure includes costs incurred to secure growth in customers or revenue units or to provide service enhancements , other than those related to cpe .
scalable infrastructure includes equipment that controls signal reception , processing and transmission throughout our distribution network , as well as equipment that controls and communicates with the cpe residing within a customer 2019s home .
also included in scalable infrastructure is certain equipment necessary for content aggregation and distribution ( video on demand equipment ) and equipment necessary to provide certain video , high-speed internet and digital phone service features ( e.g. , voice mail and e-mail ) .
( c ) line extensions include the costs of extending our distribution network into new service areas .
these costs typically include network design , the purchase and installation of fiber-optic and coaxial cable , and certain electronic equipment .
( d ) support capital includes costs associated with the replacement or enhancement of non-network assets due to technical or physical obsolescence and wear-out .
these costs typically include vehicles , computer and office equipment , furniture and fixtures , tools , and test equipment .
( e ) upgrades include costs to enhance or replace existing portions of our cable net- work , including recurring betterments .
( f ) business services include the costs incurred related to the rollout of our services to small and medium-sized businesses .
the equipment typically includes high-speed internet modems and phone modems and the cost of installing this equipment for new customers as well as materials and labor incurred to install the cable that connects a customer 2019s business to the closest point of the main distribution net- comcast 2008 annual report on form 10-k 32 .
