Practice Listening: Fill in the Blanks (Type In) ID: #34865 Medium Neutron stars
Instructions ›
You will hear a recording. Type the missing words in each blank.
* Fill in the missing words into the blank fields
Last  year,  astronomers  observed  two  neutron  stars  collide.  A  crash    in  gravitational  waves  to  detectors  here  on  Earth.  Represented  in  sound,  you  can  hear  a  small  upwards  sweep  in  frequency,  in  the  data,  if  you  listen  closely.  Several  seconds  later,  the  first  waves  of  electromagnetic  radiation  arrived  here  on  Earth  -  the  first  time  a  collision  has  been  detected  by  both  light  and  gravitational  waves.  And  it's  in  studying  the  electromagnetic    of  the  collision  that  astrophysicists  have  gotten  a  far  better    of  what  really  happened  after  those  binary  neutron  stars  merged,  130  million  light  years  away.  "Oh  yeah,  absolutely,  so  it  gives  us  an  understanding  of    all  the  nitty-gritty  of  what's  going  on  after  the  merger  takes  place."  Kunal  Mooley,  an  astrophysicist  at  Caltech.  First,  he  says,  the  stars  collided,  creating  a  massive,  black  hole  like  object,  which  started  sucking  up  the  cloud  of  neutron-rich  cosmic  debris  left  over  from  the  crash.  But  its    was  limited.

AI explanationShows the answer. Tap to open.
Correct answer: transmitted

Explanation: The speaker says "crash transmitted in gravitational". It already happened, so the word ends in ed.

Meaning: "transmitted" means sent out or passed on.

Wrong options:

  • transmited: It leaves out the "t". Write "transmitted". Only the exact spelling gets the mark.
  • transferred: Transferred means moved from one place to another, not sent as waves.
Correct answer: echoes

Explanation: You hear "electromagnetic echoes of". It comes after "electromagnetic", so you need a word for a thing.

Meaning: "echoes" means repeated shows or after-effects of the collision.

Wrong options:

  • echos: It leaves out the "e". Check the letters: "echoes". A small spelling mistake loses the mark.
Correct answer: glimpse

Explanation: Listen for "better glimpse of what". The sentence needs a short view word.

Meaning: "glimpse" means a quick view or small idea of something.

Wrong options:

  • glimse: It leaves out the "p". Check the letters: "glimpse". A small spelling mistake loses the mark.
Correct answer: basically

Explanation: On the recording you hear "understanding of basically all". You need a word that tells how or how much, so it ends in ly.

Meaning: "basically" means mostly or in most ways.

Wrong options:

  • basicly: It leaves out the "al". Check the letters: "basically". A small spelling mistake loses the mark.
Correct answer: appetite

Explanation: Listen again to "its appetite was limited". It comes after "its", so you need a word for a thing.

Meaning: "appetite" means the desire to take in or consume more material or fuel.

Wrong options:

  • appitite: It has "i" where the word has "e". Write "appetite". Only the exact spelling gets the mark.
