Input: Article: Underpinning Houston's land surface are unconsolidated clays, clay shales, and poorly cemented sands up to several miles deep. The region's geology developed from river deposits formed from the erosion of the Rocky Mountains. These sediments consist of a series of sands and clays deposited on decaying organic marine matter, that over time, transformed into oil and natural gas. Beneath the layers of sediment is a water-deposited layer of halite, a rock salt. The porous layers were compressed over time and forced upward. As it pushed upward, the salt dragged surrounding sediments into salt dome formations, often trapping oil and gas that seeped from the surrounding porous sands. The thick, rich, sometimes black, surface soil is suitable for rice farming in suburban outskirts where the city continues to grow.

Now answer this question: Houston's geology was formed from river deposits from the erosion of what mountains?

Output: Rocky Mountains

Input: Article: The Ems telegram had exactly the effect on French public opinion that Bismarck had intended. "This text produced the effect of a red flag on the Gallic bull", Bismarck later wrote. Gramont, the French foreign minister, declared that he felt "he had just received a slap". The leader of the monarchists in Parliament, Adolphe Thiers, spoke for moderation, arguing that France had won the diplomatic battle and there was no reason for war, but he was drowned out by cries that he was a traitor and a Prussian. Napoleon's new prime minister, Emile Ollivier, declared that France had done all that it could humanly and honorably do to prevent the war, and that he accepted the responsibility "with a light heart." A crowd of 15–20,000 people, carrying flags and patriotic banners, marched through the streets of Paris, demanding war. On 19 July 1870 a declaration of war was sent to the Prussian government. The southern German states immediately sided with Prussia.

Now answer this question: What telegram had the intended effect on French public opinion?

Output: Ems telegram

Input: Article: After a lengthy period of formal racial segregation in the former Confederacy following the Reconstruction Era, and bans on interracial marriage in various parts of the country, more people are openly forming interracial unions. In addition, social conditions have changed and many multiracial people do not believe it is socially advantageous to try to "pass" as white. Diverse immigration has brought more mixed-race people into the United States, such as the large population of Hispanics identifying as mestizos. Since the 1980s, the United States has had a growing multiracial identity movement (cf. Loving Day). Because more Americans have insisted on being allowed to acknowledge their mixed racial origins, the 2000 census for the first time allowed residents to check more than one ethno-racial identity and thereby identify as multiracial. In 2008 Barack Obama was elected as the first multiracial President of the United States; he acknowledges both sides of his family and identifies as African American.

Now answer this question: When did the US begin to experience a growing multiracial identity movement?

Output:
Since the 1980s, the United States has had a growing multiracial identity movement
