Q1 Many researchers avoid expressing sentences with personal pronouns such as I, you, we. Rather, they resort to the passive tense and add clutter with words and expressions like It should be noted that or It is suggested that. The former expression appears more than 2100000 times in Google Scholar([1]) and the latter over 710000 times. In the 500 most-cited articles and letters from Science in 2013 and the top 500 from Nature, how many times does we or our appear?([2,3]) (a) more than 2000 (2004) (b) between 1000 and 2000 (c) between 500 and 1000 (d) between 250 and 500 (e) less than 250
