The correct answer is: a. A site in DNA that recruits the RNA Polymerase
Promoters are regions of DNA molecule located near the transcription start codons of genes, usually upstream on the DNA with the function to initiate DNA transcription. Promoters contain specific DNA sequences (e.g. TATA boxes) that are binding sites for the enzyme RNA polymerase and transcription factors that recruit RNA polymerase. Transcription factors can regulate gene expression and act as activators or repressors depending on sequences that attach to specific promoters.

Answer: The troubling reality of humanity's over-sized and still expanding population and create highly effective programs to solve the problem. Our efforts focus on specific attitudinal drivers of ongoing rapid population growth.
Explanation: In fact, world population growth remains totally unsustainable over 230,000 people are added to world population each day. That is a net gain - births minus deaths. But few people understand the true drivers of this increasing world population. Even fewer know how to effectively intervene. Long established and widely practiced social norms low status of women & girls, bias against modern contraception, and large ideal family size are the strongest drivers rapid growth of the population. If somebody tries to tell you that population growth is "slowing down," ask them to explain the graphic on the left.
