Here is a question about this article: Hokkien has one of the most diverse phoneme inventories among Chinese varieties, with more consonants than Standard Mandarin or Cantonese. Vowels are more-or-less similar to that of Standard Mandarin. Hokkien varieties retain many pronunciations that are no longer found in other Chinese varieties. These include the retention of the /t/ initial, which is now /t/ (Pinyin 'zh') in Mandarin (e.g. 'bamboo' is tik, but zhu in Mandarin), having disappeared before the 6th century in other Chinese varieties.
What is the answer to this question: What do Hokkein varieties retain that are no longer found in other Chinese varieties?
****
So... many pronunciations

Here is a question about this article: In the case of the ring-porous hardwoods there seems to exist a pretty definite relation between the rate of growth of timber and its properties. This may be briefly summed up in the general statement that the more rapid the growth or the wider the rings of growth, the heavier, harder, stronger, and stiffer the wood. This, it must be remembered, applies only to ring-porous woods such as oak, ash, hickory, and others of the same group, and is, of course, subject to some exceptions and limitations.
What is the answer to this question: What is the only kind of wood that will definitely be harder and stronger when it grows faster?

So... ring-porous

Here is a question about this article: The FA permitted artificial turf (3G) pitches in all rounds of the competition from the 201415 edition and beyond. Under the 2015-16 rules, the pitch must be of FIFA One Star quality, or Two Star for ties if they involve one of the 92 professional clubs. This followed approval two years previously for their use in the qualifying rounds only - if a team with a 3G pitch progressed to the competition proper, they had to switch their tie to the ground of another eligible entrant with a natural grass pitch. Having been strong proponents of the surface, the first match in the proper rounds to be played on a 3G surface was a televised first round replay at Maidstone United's Gallagher Stadium on 20 November 2015.
What is the answer to this question: How many professional clubs are there?

So...
92
