You often hear the thunder after you see a bolt of lightning. This is because sound
                        travels slower than light. The farther away the lightning is, the longer it takes for
                        you to hear the thunder. You can tell how far away the lightning is. You can count
                        the seconds between the lightning and the sound of the thunder it makes. Sound
                        travels about 1 mile (about 1.6 kilometers) every 5 seconds. If you count slowly to
                        5 and hear thunder, the lightning bolt was about 1 mile away. If you count to 15
                        before you hear thunder, the lightning bolt was 3 miles away.


                        11. Paragraph 2 of the text above tells you about … .
                           a.  the heat of the sun surface
                           b.  the loud sound of  air
                           c.  how the thunder happens.
                           d.  the sun that shines the air.

                        12. We often hear the thunder after seeing the lightning because ...
                           a.  the light travels faster the sound.
                           b.  the thunder is very hot to feel.
                           c.  the lightening is farther away.
                           d.  the air rushes to heat the earth.

                        13. How many miles away from you is the lightning bolt if you count the sound of
                           thunder at 30 seconds?
                           a.  7                                     c.  5
                           b.  6                                     d.  4

                        14. The word “it” in the sentence “A bolt of lightning can make the air around it
                           as hot as 18,000° Fahrenheit (10,000° Celsius.”refers to … .
                           a.  the air                               c. the lightning
                           b.  the sun                               d. the sound

                                                            Bees  are  flying  insects  closely  related  to
                                                            wasps and ants, and are known for their role
                                                            in pollination and for producing honey and
                                                            beeswax.  There  are  nearly  20,000  known
                                                            species of bees in nine recognized families
                                                            though many are undescribed and the actual
                        number is probably higher. They are found on every continent except Antarctica,
                        in every habitat on the planet that contains insect-pollinated flowering plants.
                        Bees have a long proboscis (a complex "tongue") that enables them to obtain the
                        nectar  from  flowers.  They  have  antennae  almost  universally  made  up  of  13
                        segments in males and 12 in females, as is typical for the super family. Bees all
                        have two pairs of wings, the hind pair being the smaller of the two; in a very few
