You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.
Solution: Who believes Fagin's gang make wallets and handkerchiefs?.
Why? This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.

New input: Passage: The top employer in the city is the city government itself, employing 5.3% (25,000+ people) of the city's population, followed by UCSF with over 22,000 employees. Third—at 1.8% (8,500+ people)—is California Pacific Medical Center, the largest private-sector employer. Small businesses with fewer than 10 employees and self-employed firms make up 85% of city establishments, and the number of San Franciscans employed by firms of more than 1,000 employees has fallen by half since 1977. The growth of national big box and formula retail chains into the city has been made intentionally difficult by political and civic consensus. In an effort to buoy small privately owned businesses in San Francisco and preserve the unique retail personality of the city, the Small Business Commission started a publicity campaign in 2004 to keep a larger share of retail dollars in the local economy, and the Board of Supervisors has used the planning code to limit the neighborhoods where formula retail establishments can set up shop, an effort affirmed by San Francisco voters. However, by 2016, San Francisco was rated low by small businesses in a Business Friendliness Survey.Like many U.S. cities, San Francisco once had a significant manufacturing sector employing nearly 60,000 workers in 1969, but nearly all production left for cheaper locations by the 1980s. As of 2014, San Francisco has seen a small resurgence in manufacturing, with more than 4,000 manufacturing jobs across 500 companies, doubling since 2011. The city's largest manufacturing employer is Anchor Brewing Company, and the largest by revenue is Timbuk2.
Solution:
Who is San Francisco's top employeer?
