Can someone help me with my Spanish is it fue or era btw we are dealing with imperfect and preterite tense

ummmthings that are different in peru than in the united states:

1. granola bars: they are not made of granola. they are made of quinoa and other grains that remind me of the millet i feed my birds at home. they have the texture of styrofoam but are cheap and comparatively healthy.

the correct answers are:

[b]:   " fray bentos " .

[c]:   " paysandú   " .

[d]:   " colonia del sacramento   " .

[e]: " salto " .

[g]:   " nueva palmira " .
