A galaxy is bigger than a black hole.
That depends exactly how you interpret the term "strong". In its vicinity, the black hole distorts space more than anything that is NOT a black hole; so much that nothing can get out of the black hole. But at some standard distance, a galaxy, for example, would have more gravitational attraction than a black hole, simply because it has more mass. At least, so far no black hole of the mass of an entire galaxy has been found.That depends exactly how you interpret the term "strong".

The nearest black hole to the Earth is about 9.7 light years away!
Sure. For example, a galaxy has a larger mass.
Yes. VY Canis Majoris is about 4 billion kilometers across. This is comparable to the diameter of the event horizon of a 1.3 billion solar mass black hole. Black holes much larger than this have been detected in the centers of distant galaxies.
Almost every galaxy has a super massive black hole in its centre and this fact is widely accepted now days . Milky way galaxy also have a super massive black hole of its own, weighing more than 4 million times more than our sun's mass. Andromeda galaxy is our nearest neighbour having a super massive black hole in its centre weighing 114 million solar masses .
All galaxy's contain one or up to 2 (that we know of) super massive black holes. these keep all the stars, planets everything together. Everything in the galaxy orbits the super massive black hole. It is also a theory that there is a much larger black hole than a super massive black hole, (about a thousand times bigger) in the centre of the universe.
No. At least, the black holes in existence so far are much smaller in size, and have much less mass, than a galaxy. However, note that the black hole in the center of the largest galaxies can have more mass (but not more diameter) than some dwarf galaxies.
No - The volume of the Milky Way galaxy is larger than the volume of its host black hole. The accumulated mass of the Milky Way galaxy is greater than the mass of its host black hole. The density of the Milky Way galaxy is much smaller than the density of its host black hole.
Yes. Most, of a galaxy's mass is stars and nebulae, not black holes.
Yes. Though in theory black holes can have any size, the actual black holes that have been observed, including the so-called supermassive black holes, are tiny when compared to a galaxy. Note that the largest black hole can have the mass - but not the size - of a small galaxy.
If you mean that somehow the black hole can be removed or flung out of the galaxy than, no it can't, because the galaxy (or more specifically all the stars, gases, and asteroids, and dust clouds) orbit around the central black hole in a galaxy, they are just moving to fast and to far away to be pulled into the black hole, and if a black hole where to move the surrounding stars and debris would follow is path.
the centre of the milky way is believed to be a super massive black hole .the black hole, said to be 27000 light years from the earth, is 4 million times bigger than our sun .It is believed that almost every galaxy have a super massive black hole as its centre
I don't think that either of these stars "have" a black hole.

Our Universe is bigger, than a galaxy.
Maby the universe
The quasar is bigger. A quasar is a disk of superheated matter that surrounds a supermassive black hole. The mass of the black hole may be greater than that of the disk, but it is compacted into a smaller space.
