Input: Article: Catalan shares many traits with its neighboring Romance languages. However, despite being mostly situated in the Iberian Peninsula, Catalan differs more from Iberian Romance (such as Spanish and Portuguese) in terms of vocabulary, pronunciation, and grammar than from Gallo-Romance (Occitan, French, Gallo-Italic languages, etc.). These similarities are most notable with Occitan.

Now answer this question: What other Iberian Romance languages are found in this area?

Output: Spanish and Portuguese

Input: Article: Most common glass contains other ingredients to change its properties. Lead glass or flint glass is more 'brilliant' because the increased refractive index causes noticeably more specular reflection and increased optical dispersion. Adding barium also increases the refractive index. Thorium oxide gives glass a high refractive index and low dispersion and was formerly used in producing high-quality lenses, but due to its radioactivity has been replaced by lanthanum oxide in modern eyeglasses.[citation needed] Iron can be incorporated into glass to absorb infrared energy, for example in heat absorbing filters for movie projectors, while cerium(IV) oxide can be used for glass that absorbs UV wavelengths.

Now answer this question: What is the benefit of thorium oxide in addition to its refractive index?

Output: low dispersion

Input: Article: human activities are more likely to affect the habitat in areas of permanent water (oases) or where water comes close to the surface. Here, the local pressure on natural resources can be intense. The remaining populations of large mammals have been greatly reduced by hunting for food and recreation. In recent years development projects have started in the deserts of Algeria and Tunisia using irrigated water pumped from underground aquifers. These schemes often lead to soil degradation and salinization.

Now answer this question: What activities from these mammals will likely affect   habitat areas?

Output:
human activities
