Let’s take the charitable view and call this a typo on Yahoo! News:
Funny thing about typos: The reader can’t always figure out what the writer means. Is it several students who develop the robotic arm? Or is it one student who develops it?
If you’re responsible for this gaffe on Yahoo! omg!, I recommend you plead the Fifth to avoid the Grammar Slammer:
The verb just can’t seem to get it together with the subject. It should be the past tense pleaded or the present tense pleads.
If you read the Yahoo! front page as often as I do, you kinda expect a grammatical error, like this mismatch of a subject and its verb:
Maybe the writer was misled by the list of weathery things between the verb and its subject, which is mix. I can understand a mistake like that — from a fourth grader.
In the pantheon of horrible mismatches, this incorrect subject-verb combo on Yahoo! Screen tops the list:
If the writer had been keeping up with Italian, this mismatch of subject and verb wouldn’t have appeared on Yahoo! omg!:
If there’s just one photog, that’s a paparazzo; more than one is paparazzi. The word paparazzo is taken from the name of a character in La Dolce Vita, a 1960 film by Federico Fellini.
No, each of those iconic characters is portrayed… That’s what the writer for Yahoo! Movies should have written:
When the subject of a clause is each, the verb must be singular.
OK, folks at Yahoo! Music, listen carefully: The singer’s name is Natalia Kills and even though her name ends in an S, she’s not a plural, she’s just one person. Just like Joe Jonas is not a plural of Joe Jona. So, when you’re trying to figure out if Natalia Kills plays music or Natalia Kills play music, go with the former.
Fear that the editors for the Yahoo! front page are grammatically challenged seems to have been justified:
The subject of the verb seem is fear; therefore it seems to me that seem should be seems.
