TASK DEFINITION: In this task, you are given Wikipedia articles on a range of topics, we ask you to write a question based on the content of the articles that can be answered in a binary manner i.e. True or False.
PROBLEM: Semen analysis -- Sperm count, or sperm concentration to avoid confusion with total sperm count, measures the concentration of sperm in a man's ejaculate, distinguished from total sperm count, which is the sperm count multiplied with volume. Over 15 million sperm per milliliter is considered normal, according to the WHO in 2010. Older definitions state 20 million. A lower sperm count is considered oligozoospermia. A vasectomy is considered successful if the sample is azoospermic (zero sperm of any kind found). Some define success as when rare/occasional non-motile sperm are observed (fewer than 100,000 per millilitre). Others advocate obtaining a second semen analysis to verify the counts are not increasing (as can happen with re-canalization) and others still may perform a repeat vasectomy for this situation.

SOLUTION: is sperm concentration the same as sperm count

PROBLEM: Fourth television network -- The October 1986 launch of the Fox Broadcasting Company was met with ridicule. Despite the industry skepticism and initial network instability (due to its early struggles in launching hit programs), the Fox network eventually proved profitable by the early 1990s, becoming the first successful fourth network and eventually surpassing the Big Three networks in the demographics and overall viewership ratings by the early 2000s.

SOLUTION: by the mid-1980s fox had emerged as a viable fourth network
