Given a question and a context passage, generate the answer having the word or phrase from the context passage. Here, the answer should be a shortest continous span from the passage.

Q: Context: The U.S. Census for 2010 reported 332,199 households in Indianapolis, with an average household size of 2.42 and an average family size of 3.08. Of the total households, 59.3% were family households, with 28.2% of these including the familys own children under the age of 18; 36.5% were husband-wife families; 17.2% had a female householder (with no husband present) and 5.6% had a male householder (with no wife present). The remaining 40.7% were non-family households. , 32% of the non-family households included individuals living alone, 8.3% of these households included individuals age 65 years of age or older. 
 Question: Which group from the census is smaller: non-family households or husband-wife families?

A: husband-wife families

Q: Context: In late July, Danzig was re-inforced by a Dutch garrison, and a combined Danish and Dutch fleet broke the naval blockage imposed on Danzig by Charles X Gustav. On 28-30 July, a combined Brandenburgian-Swedish army was able to defeat the Polish-Lithuanian army in the Battle of Warsaw, forcing John II Casimir to retreat to Lublin. In August, Alexis' army took Livonian Kokenhausen , laid siege to Riga and Dorpat and raided Estonia, Ingria and Kexholm. On 4 October, John II Casimir stormed eczyca in Greater Poland before heading for Royal Prussia, and on 8 October, Wincenty Korwin Gosiewski with 12,000 to 13,000 Lithuanian and Crimean Tartar cavalry overran a Brandenburgian-Swedish force in the Battle of Prostken in Ducal Prussia. Gosiewski then ravaged Ducal Prussia, burning 13 towns and 250 villages, in a campaign that entered folklore because of the high death toll and the high number of captives deported to the Crimea. On 22 October, Gosiewski was defeated by Swedish forces in the Battle of Filipow and turned to Lithuania. Also on 22 October, besieged Dorpat surrendered to Alexis, while the Russian siege of Swedish-held Riga was lifted. John II Casimir meanwhile took Bromberg and Konitz in Royal Prussia, and from 15 November 1656 until February 1657 stayed in Danzig, where a Swedish siege had to be lifted due to Dutch intervention, just 55 kilometers away from Charles X Gustav's quarters in Elbing. 
 Question: Who won the Battle of Warsaw?

A: brandenburgian-swedish

Q: Context: Dapivirine, formerly known as TMC 120, is a poorly-water soluble anti-HIV drug, currently being developed as a vaginal microbicide. The clinical use of this drug has been limited due to its poor solubility. The aim of this study was to design solid dispersion systems of Dapivirine to improve its solubility. Solid dispersions were prepared by solvent and fusion methods. Dapivirine release from the solid dispersion system was determined by conducting in-vitro dissolution studies. The physicochemical characteristics of the drug and its formulation were studied using Differential Scanning Calorimetry (DSC), powder X-ray Diffraction (XRD), Fourier-transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM). A significant improvement in drug dissolution rate was observed with the solid dispersion systems. XRD, SEM and DSC results indicated the transformation of pure Dapivirine which exists in crystalline form into an amorphous form in selected solid dispersion formulations. FTIR and HPLC analysis confirmed the absence of drug-excipient interactions. Solid dispersion systems can be used to improve the dissolution rate of Dapivirine. This improvement could be attributed to the reduction or absence of drug crystallinity, existence of drug particles in an amorphous form and improved wettability of the drug. 
 Question: Which infection can be prevented with Dapivirine?

A:
hiv
